What is Hardening and 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.

Export Duty imposed on iron-ore.

RANCHI: Economists, industrialists and government officials from Jharkhand are all praise for the proposal of Union finance minister Pranab Mukherjee to levy a 20 per cent ad valorem duty on all types of outbound shipment of the key steel making raw material from the country.

The decision has earned appreciation from Jharkhand as the state has been one of the worst sufferers of iron export. Former chief minister Madhu Koda and his close aides were able to create an empire worth more than Rs 4,000 crore, a major part of which came allegedly for covertly supporting smuggling of iron ore and illegal mining.

Till now, iron ore attracts an export duty of 15 per cent in the case of lumps (high quality) and five per cent in the case of fines (low grade). India is the world’s third largest iron ore exporter. Around 218 mt of iron ore was produced in 2009-10 and almost half of it was exported.

Sources in state mining department said that during 2006-08 a number of iron ore mine lease holders intentionally crushed high quality ore to convert it into fines and exported it. “Since it has patronage of high profile people, the business flourished. Now when the government has decided to levy a 20 per cent ad valorem duty on all grade it will act as a deterrent,” said a government officer.

The decision is expected to generate additional revenue of around Rs 15,000-20,000 crore and contribution of Jharkhand will not be less than Rs 5,000 crore if export continues at the same rate.

India has around 25 billion tonnes of iron ore reserves scattered mainly across Jharkhand, Orissa, Chhattisgarh and Karnataka. Professor Prabal Sen of XLRI School of Business and Human Resources said the decision is going to help local industries and boost the economy of Jharkhand in particular. It will act as a deterrent for those involved in illegal trade.

Chairman-cum-managing director of Heavy Engineering Corporation, G K Pillai, too, appreciated the decision taken by the finance minister. “The decision to withdraw export duty on iron ore pellets will encourage industrialisation. More industries will come up as the decision encourages exports only after due value-addition,” said Pillai in his initial reaction to the budget.

Narrow Strips – Hardened & Tempered.

BTC, with its own dedicated furnace for narrow strips has now become fully equipped to meet the demand of the growing automobile industry.

With state of the art furnace, edge profile machines, slitting line and polishing machine, we are now capable of manufacturing strips as narrow as 3mm width with a thickness range of .15mm upto 2.00mm.

The installed capacity is about 40MT per month per month and we have already achieved 80% capacity within a matter of 3 months. The quality is approved in the auto sector and a substantial quantity is also exported.

Ou next step is to install a dedicated line for heat treatment of stainless steel.
