304L Stainless Steel Seamless Pipe Tube
Product Details
Introduction
304L stainless steel is a kind of general low carbon stainless steel, it is widely used to make for a good comprehensive performance, corrosion resistance ,form-ability of equipment and parts.
It has corrosion resistance and good heat resistance, low temperature resistance and good mechanical properties. No heat treatment hardening phenomenon (non-magnetic, using temperature to -196 ℃ ~ 800 ℃).
Applied to the grain boundary corrosion resistant requirements of high chemical industry, coal, oil field open machine, building materials with heat-resistant parts and heat treatment which are difficult parts.
Technical Parameter
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
304L,It belongs to the Austenitic steel,which is applied to the grain boundary corrosion resistant requirements of high chemical industry, coal, oil field open machine, building materials with heat-resistant parts and heat treatment which are difficult parts.
