The annealed chromium-nickel-molybdenum steel AISI 316 / AISI 316 L is a stainless, austenitic steel with low carbon content. Due to the addition of 2 – 2.5% molybdenum, the corrosion resistance of AISI 316 / AISI 316 L is significantly better compared to standard austenitic steels.

AISI 316 L stainless steel is resistant to intergranular corrosion in the welded condition! No resistance to sea water! With polished surface the best corrosion resistance is given.

International identifiers:

SS 2343, SS 2348, SS 2553, ASTM 316L, UNS S31603, AFNOR Z2CND17-12, BS 316S12, UNI X2CrNiMo1712, JIS SUS316L, GOST 03Ch17N13M2, GB 022Cr17Ni12Mo2, 1.4404

Applications:

Aisi 316 is mainly used in automotive industry, chemical industry, construction industry, petroleum industry, petrochemical industry, engineering, decorative and kitchen equipment, food industry, aviation, electronic equipment, medical and pharmaceutical industry.

Properties:

welding qualification medium
mechanization 6 (1 = bad – 10 = very good)
polishing yes
corrosion resistance low
corrosion class: 4 ( 0 = bad – 5 = good)

Forging: During the forging process, slow heating to approx. 1150°C – 1180°C takes place in order to forge in a temperature range of 900°C – 1180°C. Subsequently, air or water cooling takes place. A reduction in corrosion resistance is achieved by scale or tarnish.

Welding: AISI 316 / AISI 316 L stainless steel can be welded well with and without filler metal. An interpass temperature of 200°C should not be exceeded. No heat treatment is required afterwards. The resistance to intergranular corrosion is not affected by the heat input during welding.

Corrosion resistance: Due to its low carbon content, AISI 316 / AISI 316 L is resistant to intergranular corrosion, but is not resistant to seawater. Excellent corrosion resistance is given in natural environmental media and moderate chlorine and salt concentrations.

Cold forming: AISI 316 / AISI 316 L is suitable for cold forging

Benefits of sawn cuts:

Due to mechanical processing with the saw, the material structure shows much lower unintentional deformation and material hardening than, for example, oxyfuel cutting. Therefore, the already machined piece from the saw has a homogeneous structure at the edge, which remains unchanged in the further processing of the material. This circumstance allows for immediate finishing work with milling or drilling of the piece, without the need for additional annealing or similar processes.
