Chemical Composition And Application Of SS 316L Sheet

Stainless steel grade 316L is a low carbon version of grade 316L stainless steel. It has the same corrosion resistance and strength as 316 Stainless Steel, but can produce stronger welds because of its low carbon content. The following datasheet provides an overview of stainless steel grade 316L. Element Content Precent Iron, Fe Balance Chromium, Cr 18-20 Nickel, Ni 11-15.

Manufacturing Process

Machining stainless steel grade 316L requires low speeds and constant feeds to reduce its tendency to work hard. This steel is stronger than grade 304 stainless steel with a long stringy chip; however, the use of chip breakers is recommended. Welding can be done using most conventional fusion and resistance methods. Oxyacetylene welding should be avoided. AWS E/ER 316L filler metal is recommended.
Conventional hot working processes can be performed. The material should be heated to 1149-1260°C (2100-2300°F); however, it should not be heated below 927°C (1700°F). To optimize corrosion resistance, post-work annealing is recommended.
Shearing, stamping, deep drawing, and stamping are possible with 316L grade stainless steel, and post-treatment annealing is recommended to remove internal stresses. Annealing is performed at 1010-1121 ° C (18502050 ° F), which should be followed by rapid cooling.
Grade 316L SS does not respond to heat treatment.

Features of SS 316 Sheet

Stainless Steel 316L sheet is the low-carbon derivative of SS 316.
The metal maintains its high strength and strong corrosion-resistance; however, the carbon content does have several effects.
Stainless Steel 316L sheet has greater strength under welding; its products are stronger.
Stainless steel 316L sheet does not respond or harden from heat treatments.
