Description: Stainless steel pipe used for decoration and industrial life, many people on the market for making stair handrail, protective Windows, railings, furniture, etc. Accounted for about 16% 8% of the total amount of steel a, its application range is very wide in the national economy.
And because the steel pipe has a hollow cross section which is ball valve manufacturer suitable for liquid, gas, and solid pipeline; At the same time, compared with the same weight of round steel, steel pipe section flexural torsional strength coefficient is big, big, so all kinds of mechanical and architectural structure have become the important.
Materials. The company mainly produces inventory sales 304, TP304, 304 l, 321, 316, TP316L TP321, thick wall stainless steel seamless tube, stainless steel seamless steel tube TP347H boiler, 13296 stainless steel heat exchange tube, S32205 stainless steel seamless tube, S32750/2507 stainless steel seamless tube, non-standard thick wall pipe and pipe fittings. Products are widely used in petroleum, chemical, natural gas, electric power equipment manufacturing and mechanical equipment manufacturing and other industries. The company has a model for GZK42320 digital-control sawing, product ruler.
Inch cut retail, generation of processing can be zero, big zero cut 630 mm, 80 mm thick wall thickness. 304, TP304, 304 l, 321, 316, TP316L TP321, thick wall stainless steel pipe perennial inventory, complete specifications, low prices, quality assurance, can scale cutting.
What is the corrosion resistance of 304 stainless steel plate?
304 stainless steel plate is a kind of general and very popular on the 14 needle valve market of stainless steel materials, it has very good corrosion and corrosion resistance, high temperature resistance and good resistance to intergranular corrosion. Antirust performance is more than 200 series products to strengthen, high temperature resistance Performance also can reach 1000-1200 degrees.
304 stainless steel plate products have strong corrosion resistance, for ordinary alkali solution and organic acid, inorganic acid have good corrosion resistance, it is a kind of high alloy steel, can resist air or chemical corrosion in the corrosive medium. Stainless steel has the aesthetic The surface of the pleasant and good corrosion resistance. It does not need to surface treatment such as electroplating, to give the surface of the stainless steel overall performance. One aspect of the steel, usually called stainless steel.
Correct heat treatment can eliminate the welding residual stress, also does not affect the coating corrosion resistant function. The method is:
1. Heat treatment to the big order or stiffness of stainless steel plate welded components.
2. Welding shall be at the bottom end, internal and surface quality detection bait seam San all qualified after heat treatment, and temperature not to surpass 400 degrees.
3. Using this temperature welding post-processing, can make the residual 38 needle valve stress reduced by 40%. It won't affect the turbidity resistance function of the cladding of stainless steel.
4. Complete rear weldable isolation layer in the heat treatment and cladding of stainless steel plate. After the cladding welding, without any heat treatment.
