Introduction
316L stainless Steel adds Mo (2-3%), so it has excellent corrosion resistance and high temperature strength; SUS316L carbon content is lower than SUS316, therefore, the resistance to inter-granular corrosion resistance is better than SUS316: high temperature creep strength is high. It can be used in harsh conditions.good strain hardening and non-magnetic.
1) cold-rolled product appearance, good gloss, beautiful;
2) the addition of Mo, corrosion resistance, especially resistance to pitting corrosion;
3) excellent high temperature strength
4) Excellent hardening (after processing weakly magnetic)
5) solid solution state non-magnetic;
6) relative to 304 stainless steel, it has higher prices.(10Ni)
Welding
Excellent weldability by all standard fusion and resistance methods, both with and without filler metals. Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L.
316L stainless steel is not generally weldable using oxyacetylene welding methods.
Machining
316L stainless steel tends to work harden if machined too quickly. For this reason low speeds and constant feed rates are recommended.
316L stainless steel is also easier to machine compared to 316 stainless steel due its lower carbon content.
Hot and Cold Working
316L stainless steel can be hot worked using most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260°C, and certainly should not be less than 930°C. Post work annealing should be carried out to induce maximum corrosion resistance.
Most common cold working operations such as shearing, drawing and stamping can be performed on 316L stainless steel. Post work annealing should be carried out to remove internal stresses.
Hardening and Work Hardening
316L stainless steel does not harden in response to heat treatments. It can be hardened by cold working, which can also result in increased strength.

Seamless steel pipe
Steel ingots or solid tube through the perforation of the capillary, and then by hot-rolled, cold-rolled or cold dial made. with hollow cross-section, a large number of pipes for the transmission fluid. is generally molten state of the molten steel through the annular slit back out and then processed by the tensile molding process, so there is no weld. In terms of performance, especially pressure on the ability of welded steel pipe has greatly improved, it is often used for high-voltage equipment. Such as hydraulic equipment, piping connections.
Welded pipe
A steel or steel plate bending deformation into a circular and then welded into the surface of the steel pipe joints. Welded pipe used in the blank is steel or strip.The welding seam of welded steel pipe is the weak link, and the quality of weld is also the main factor affecting its overall performance. Welded steel pipe in the north of the China people living in general have had water pipes or heating pipes in the winter was the experience of cold explosion, where the explosion is generally weld.
Application
316L is suitable for mixing equipment, chemicals, fuels, papermaking, oxalic acid, waste production equipment, photography, food industry, coastal facilities., ect.
Our cold rolled coil and sheet are a very popular choice for applications from consumer goods and prestigious building to corrosion,resistantfor the process industry.
Hot rolled coil and sheet are used in application such as the production of process plant equipment and a host of other application.
