Grade C125 Steel Strips

Earlier, import was the only option for this material, which was a big hassle. But now, we at BTC are regularly keeping stock of this material in various sizes, and can offer the same off the shelf.

Range:
Thickness: 0.07 mm to 4.00 mm
Width: 8 mm to 500 mm (in thickness lower than 0.6 mm, 4 mm wide material can also be supplied)
Hardness: Fully annealed material with a maximum hardness of 200 VPN & special temper material with hardness ranging from 230 VPN to 285 VPN.

This is a very special grade of steel and is mainly used for making those components where very high tensile strength & yield stress is required. It can achieve hardness of up to 58 HRC Rockwell after Hardening & Tempering.

Application: Mainly used for making Surgical Blades i.e. Scalpels, Metal Cutting Bandsaws, Knitting Needles .etc.

JSW Steel profits fall drastically due to weak demand.

JSW Steel has registered 56.4% fall in its Q1 of FY19-20 (April-June) consolidated net profit at Rs 1,028 crore on the back of lower sales volumes due to subdued steel demand. The company had reported profit of Rs 2,366 crore in the same period last fiscal.

Even though the company maintained its annual guidance in production, which was up three percent, its sales were down by two percent. Revenue of the company declined 3.4 percent at Rs 19,812 crore against Rs 20,519 crore.

The demand slowdown has led to higher inventory levels. While overall, the inventory was at 1.2 million tons, up 3 lakh tons from a year ago, the finished goods inventory increased to 25 days, from the otherwise 20 days.

But the company is hopeful of demand picking up in the coming quarters on the back of higher Government spending on infrastructure.

Sales improve in the first quarter: Tata Steel

Tata Steel India said its sales in the first quarter of FY20 improved 16% to 3.87 million tonne over the previous year even as liquidity issues and rural stress that impacted domestic consumption, primarily with consolidation of Tata Steel BSL Ltd. for the full quarter.

Production went up 20 per cent to 4.37 million MT in the Q1 against 3.64 million MT with consolidation of Tata Steel BSL for the full quarter due to higher capacity utilisation at both Tata Steel standalone and Tata Steel BSL Ltd.

On the other hand, steel prices across many geographies declined in the first quarter. Input costs too have spiked with a sharp rise in iron ore prices due to supply disruptions and elevated coking coal costs. As a result, market spreads for steel producers globally have been affected.

India’s ambitions on growing steel productions.

Reportedly, Economic Survey 2018-19 has estimated India’s steel output to hit 128.6 million tonne by 2021 and reach 140 million tonne by 2023, on the back of investments in infrastructure, construction and automobile sectors.

Press Trust of India says “With huge investments in infrastructure, construction and automobile sector, steel demand and corresponding consumption is growing at an average of 7.4 per cent. This will lead steel production to go up to 255 million tonnes by 2030 and per capita steel consumption to 160 kg.”

Crude steel production in 2018-19 stood at 106.56 million tonne, a growth of 3.3 percent over 103.13 million tonne in 2017-18. Currently, India’s per-capita consumption stands at only 69 kg, compared with the global average of 214 kg.

Spehrodization of High Carbon Steel Strips.

Spheroidite forms when carbon steel is heated to approximately 700 °C for over 30 hours. Spheroidite can form at lower temperatures but the time needed drastically increases, as this is a diffusion-controlled process. The result is a structure of rods or spheres of cementite within primary structure (ferrite or pearlite, depending on which side of the eutectoid you are on). The purpose is to soften higher carbon steels and allow more formability. This is the softest and most ductile form of steel. The image to the right shows where spheroidizing usually occurs.

Steel prices increasing rapidly.

Steel prices in India may go up for the third time in a month – a rare instance -as companies pass on the increase in iron ore rates.

According to sources, the third hike may take place on March 1. The increase will be of Rs 1,000 a ton, taking the total increase within a span of 30 days to Rs 2,750 a ton. The latest round will take price of hot rolled steel to Rs 44,200 a ton.

“Such an increase has rarely happened, it hasn’t taken place in the last eight years,” an industry official said.

Prices were hiked, by Rs 750 a ton, for the first time in the first week of February. The second increase, of Rs 1,000 a ton, came in the third week of the month.

The latest increase in steel prices comes after three consecutive months of softening rates in India, and the world over. Since November, prices had crashed, especially because of the China factor.

Demand in China, the world’s largest steel market, has softened since November, even though production has also been cut.

But an accident in a Brazilian iron ore mine owned by Vale SA, the world’s largest producer, pushed up prices of the raw material. According to reports, the accident in a dam will impact about 70 million tons of iron ore production.

This has led to an increase in steel prices in the global market.

Spheroidizing of carbon steel.

Spheroidite forms when carbon steel is heated to approximately 700 °C for over 30 hours. Spheroidite can form at lower temperatures but the time needed drastically increases, as this is a diffusion-controlled process. The result is a structure of rods or spheres of cementite within primary structure (ferrite or pearlite, depending on which side of the eutectoid you are on). The purpose is to soften higher carbon steels and allow more formability. This is the softest and most ductile form of steel. The image to the right shows where spheroidizing usually occurs.

As rolled hard strips – Special Temper.

These are basically as rolled hard steel strip. To achieve a desired hardness, an annealed material of suitable thickness is taken and rolled down to the required thickness, to achieve that required hardness. After rolling, the material is pinch passed and final annealing is not required. To choose the correct thickness (for reduction to the desired thickness) is a matter of expertise.

Grades: This strip is available in low, medium & high carbon grades.

Applications: It is suitable for components where formability is limited. It saves the extra annealing cost. The strip is directly punched & formed and if required sent for heat treatment.

What is hardening & tempering?

Hardening and Tempering is a thermal process that strengthens steel through a controlled heating and cooling process.

This process will result in improved mechanical properties and give a tougher more durable product. The hardening process involves heating the steel to above the critical temperature for the given grade and then rapidly cooling. Whilst this process achieves the highest mechanical stengths and hardness’s, steel in this condition is extremely brittle and therefore requires further treatment in the form of tempering. This consists of reheating the steel to a lower temperature and holding the steel at the given temperature for a given period of time. As with traditional annealing (used to soften steels) this process is conducted in an inert atmosphere to avoid oxidation.

The exact temperature and processing times vary with given grades of steel and the process is very specialized.

Steel sector on course of recovery.

After witnessing weak production globally for the five quarters in a row, signs of green shoots are finally visible in the steel sector. There was a 1.8 per cent jump in the global steel output during the September quarter, thanks to a rebound in production in China.

“Bulk of the rebound in steel prices is driven by raw material price hikes along with some contribution from a less-worse demand scenario,” the brokerage firm said.

Global and Chinese steel prices have risen 56 per cent YTD (Year to date), bringing idle capacity on stream, as operations have become more viable. However, the sector is not completely out of the woods yet, the brokerage said.
