Stainless steel can be divided into the main chemical composition, chromium nickel stainless steel, chromium manganese nitrogen stainless steel, chromium nickel molybdenum stainless steel, ultra low carbon stainless steel, high purity stainless steel; according to the performance characteristics and use of steel, such as nitric acid (nitric acid grade) stainless steel, sulfate resistant stainless steel, point corrosion resistant stainless steel, stress resistant stainless steel, high strength stainless steel, etc.According to the functional characteristics of steel classification, such as low-temperature stainless steel, magnetic-free stainless steel, easy to cut stainless steel, super plastic stainless steel, etc.It is usually classified in a gold-phase organization.According to metallographic organization into: ferrite (F) type stainless steel, martensite (M) type stainless steel, austenite (A) type stainless steel, austenite-ferrite (A-F) type double phase stainless steel, austenite-Martenite (A-M) type bipolar stainless steel and precipitation hardening (PH) type stainless steel.
What is the 430 stainless steel product?
430 Stainless steel, known as "stainless iron" in our stainless steel industry, is a general steel with good corrosion resistance, has good corrosion resistance, has better than austenitic stainless steel thermal conductivity, thermal expansion coefficient is less than austenitic, heat fatigue resistance, add stable element titanium, weld mechanical performance is good.430 Stainless steel is currently mainly used in building decoration, some home appliance parts, fuel burner parts and other room temperature or high temperature scenes.
What is the stainless iron surface 2B?
2B: represents the heat treatment, pickling, and then fine rolling to make the surface moderately bright. Because the surface is smooth, easy to grind again, make the surface more bright, widely use, such as tableware, building materials.Surtreatment with improved mechanical properties satisfies almost all applications.
Second, let's analyze it from the surface.2B refers to the surface of stainless steel, representing the fog surface, also called 2B fog surface, according to the shadow. The stainless steel on side 2B is soft, that is, the hardness HV (Vicker hardness) is at 150-200 degrees. In order, surface 2B, matte, bright, BA, and 6K,8K.BA is later a mirror (including BA).
2B Surface process: cold rolling annealing pickling and leveling.
In the past, the door and window accessories mostly used 304 stainless steel, 304 belongs to austenitic stainless steel, 430 is ferrite stainless steel.30406Cr19Ni10 (old 0Cr18Ni9), 43010Cr17 (old 1Cr17).Corrosion resistance, 304 greater than 430. On range, 304 is greater than 430. But the price of 304 is also greater than 430. 430 stainless steel, known as "stainless iron" in our stainless steel industry, has good corrosion resistance, excellent thermal conductivity than austenitic stainless steel, and 430 stainless steel added a stable chemical element titanium, weld site mechanical performance is better than 304 stainless steel.
So this time and we cooperate with the company is located in Zhaoqing city, Guangdong province, specializing in the production of hardware door and window accessories enterprise, the province has its own factory.They purchased 430 stainless iron 2B sides with a thickness of 1.8/2.0/3.0/3.5 respectively. Your company has been focused on the development, production and sales of hardware products four link sliding, four link sliding, stainless steel window, flat window hinge, stainless steel sliding, four link left and right window, flat open four links and other products processing.*** Hardware Products Co., Ltd. produces a wide variety of varieties, excellent and durable quality, unique taste and trusted and praised by consumers, not only sell well across the country, but also exported to many countries and regions in the world.
Foshan wanqing materials co., LTD. Is a collection of processing, trade in a large stainless steel circulation enterprises, adhering to the "make China steel enterprises continuous profit" mission, the company always adhere to the "honesty, fusion innovation" development concept, improve management level, condensed a loyal staff, established a "based on south China, radiation provinces, global" complete marketing network, and many domestic large stainless steel production enterprises established a solid strategic partnership.
Ten years of wind and rain process, Foshan Wanqing has gradually grown into an important part of the domestic stainless steel circulation industry, with each passing day towards the future.
