304 Stainless Steel Seamless Pipe Tube
Product Details
Introduction
304 stainless steel , also known as 18/8 ,is a kind of strong commonality and most widely used chrome - nickel stainless steel.
As a kind of widely used steel, it has good corrosion resistance, heat resistance, strength and mechanical properties at low temperature. Hot work-ability such as punching, bending is excellent.
No heat treatment hardening phenomenon . If it is in industrial pollution area, you will need to clean in time to avoid the corrosion.
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
304,It is widely used in( it has a good processing performance and weldability.)
Plate heat exchanger, corrugated pipe, household goods (1, 2 kinds of tableware, cabinets, indoor pipeline, water heater, boiler, bath), auto parts (windshield wiper, muffler, molded products), medical appliances, building materials, chemical, food industry, agriculture, Marine parts, etc.
Food grade stainless steel of 304 stainless steel for the world.
