Grade T316 and 316L
Type 316 is an austenitic chrome nickel steel with superior corrosion resistance to that of other chrome nickel steels. Widely used when exposed to chemical corrodents, as well as marine atmospheres. T-316 is generally considered non-magnetic, but can become magnetic when cold worked. In 316L, the carbon content has been lowered to .03% max. for corrosion resistance at heat affected zones from welding.
TYPICAL APPUCATIONS
Acetic acid compounds, kettles for cooking catsup, pulp and paper processing equipment, water softener tanks, and many marine applications.
