316 Stainless Steel Square Bar

Designed for use in tanks, supports and frames, enclosures, housings, engine, machinery components, and marine applications.

Description

The high corrosion resistance that the 316 stainless steel square bar offers is the reason why it’s widely used across various industries. It is non-magnetic, enabling it to be used for instruments and moving parts. This grade of stainless steel has been alloyed with chromium, nickel and molybdenum, which gives it its high resistance to high heat and corrosion caused by chlorides and warm sea water. Because of its corrosion resistant nature, it is frequently used in marine applications, such as boat fittings, valves and pump trim.
The 316L version of this alloy is immune to sensitization and is stronger (post-weld annealing isn’t required). For the 316 stainless steel, annealing is required after welding, cold working and forging. Different types of cold forming can be used for this metal, such as deep drawing, bending, cold heading, swaging and roll forming. When 316 alloys are severely cold formed, annealing is required afterward to relieve any stress that was caused. 316 stainless steels are highly ductile and tough, making it a great choice for cold forming.

Forging can be performed at a temperature set no lower than 1700 degrees F and a max between 2100 and 2300 degrees F. To maintain the corrosion resistance level, annealing should be done. It’s possible to machine this metal, but it is not as easily machined as 304 alloys. It’s advised that chip breakers and curlers be used when machining. The chip characteristics should be strong and tough.

Welding can be done with or without filler metals. The heavy welded areas should be post-weld annealed to retain corrosion resistance. Annealing should be done at a temperature range that’s between 1900 and 2100 degrees F.
