Austenite Stainless Steel.

Good to excellent corrosion resistance combined with very
good weldability and formability characterize the austenitic
stainless steels. The austenitic structure has good creep resistance and good oxidation resistance that makes them useful at elevated temperatures. Austenitic steel can also be used in cryogenic applications and is in annealed condition the only non-magnetic steel.

Stainless Steel Grade – SS310

Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Steel Grade SAE1018-Properties.

1018 is among the most commonly available grades available in the world. It is widely available in cold finished rounds, squares, flat bar and hexagons. Despite its unimpressive mechanical properties, the alloy is easily formed, machined, welded and fabricated. Due to its higher Mn content, it can, in thin sections, be hardened to Rc 42.

Applications
The alloy is a free machining grade that is often employed in high volume screw machine parts applications. It is commonly employed in shafts, spindles, pins, rods, sprocket assemblies and an incredibly wide variety of component parts.

Heat Treatment
1018 can, in thin sections be case hardened to Rc 42. In thicker sections, over 4″, Rc 28-30 can be obtained.
