High temperature oxidation resistance stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as environment and product form.

The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin, and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.

Stainless steel is a very thin, fine and stable chromium rich oxide film (protective film) formed on its surface. It prevents oxygen atoms from penetrating and oxidizing, and obtains corrosion resistance. Once this film is continuously damaged for some reason, oxygen atoms in the air or will continue to separate out, forming loose iron oxide. For a long time, stainless steel plate stainless steel coil and stainless steel belt will be provided,Stainless steel heat exchanger tube, a 20-year-old brand, has advantages in price and guaranteed quality! The metal surface is constantly corroded

.Characteristics and application 347h austenitic stainless heat strength steel has good corrosion resistance, welding performance and heat strength performance. 347h stainless steel is used for large boiler superheater, reheater steam pipeline and petrochemical heat exchanger pipe fittings.

  440— High strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach 58hrc. It belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: 440C and 440f (easy to process).

  ·Pulp and paper industry classifier,Stainless steel food tube, bleaching equipment, storage and treatment system.

Model 409 & mdash; Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

Choose the price.

Workshop cost.In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment and aging treatment before delivery. The corrosion resistance of stainless steel coil mainly depends on its alloy composition (chromium, nickel, aluminum silicon, etc.) and the interior of stainless steel coil

It has lower linear coefficient than austenitic stainless steel and is close to carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plate or lining.

Organic substances (such as melons and vegetables, noodle soup, phlegm, etc.) adhered to the surface of stainless steel constitute organic acids in the presence of water and oxygen. For a long time, the corrosion of organic acids on the metal surface.

Pursuit of excellence.  SPCDSPCD—& mdash; Cold rolled carbon steel sheet and strip for stamping, equivalent to China 08Al (1323) high quality carbon structural steel.

;- Ferromagnetism due to m transformation shall be considered in use (such as in instrument parts).

The application range is wider than that of ferritic stainless steel. Compared with ferritic stainless steel, duplex stainless steel has the following disadvantages: high alloy element content and relatively high price. Generally, ferritic stainless steel does not contain nickel.

.According to rolling, it is divided into hot rolled,Stainless steel pipe production, hot drawn and cold drawn (rolled) stainless steel pipes.

The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin, and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.

  309— It has better temperature resistance.
