Stainless steel standard thickness and actual thickness comparison table
The difference between the standard and actual thickness of stainless steel is because there may be some slight tolerances during the production of stainless steel products. The following is a brief description of the comparison table between stainless steel standard thickness and solid thickness: Thickness of stainless steel plate: There are usually several different nominal thicknesses, including but not limited to various thickness values in the range of 0.3mm to 3.0mm. These thicknesses are specified according to national standards, but may be slightly different in actual production. Thickness of stainless steel strip: Similarly, the standard thickness range can vary from 0.05mm to 3.0mm, and the actual thickness may also vary within this range. Thickness of stainless steel coils: For stainless steel coils, the standard thickness is usually between 0.3mm and 3.0mm, and the actual thickness of the coil produced will vary. To sum up, the nominal thickness of stainless steel products is an important quality indicator, but in practical applications, users should take into account the small tolerances of the product in the actual manufacturing process. Therefore, while the nominal thickness provides a guide, the actual material used should take into account the allowable tolerance range When the stainless steel...

Stainless steel quality standards
1. Stainless steel quality requirements Stainless steel is a steel material with good corrosion resistance and has a wide range of applications. The quality requirements of stainless steel mainly include chemical composition, mechanical properties, appearance quality, etc. 1.Chemical composition The chemical composition of stainless steel is mainly composed of chromium, nickel, molybdenum and other elements, of which the chromium content cannot be less than 10.5%. The chemical composition of stainless steel has an important impact on its corrosion resistance, heat resistance, mechanical properties, etc. Hua steel company has own PMI machine,we can do PMI testing to check the stainless steel sheets and plates’ chemical composition more quickly. 2.Mechanical properties The mechanical properties of stainless steel mainly include tensile strength, compressive strength, yield strength, elongation and other indicators. The mechanical properties of stainless steel materials directly affect its reliability and service life. Every time, when we prepare the stainless steel products like sheets, coils, bars, pipes, we will send customer MTC, mill certificate ,which shows mechanical properties. 3. Appearance quality The appearance quality of stainless steel refers to its surface quality requirements, which mainly include surface finish, surface condition, surface defects, etc. The qualification requirements for surface quality should comply with...

What the different for cold rolled and hot rolled
Hot rolled and cold rolled are both processes for forming steel plates or profiles, and they have a great impact on the structure and properties of steel. The rolling of steel is mainly hot rolling, while cold rolling is usually only used to produce steel products with precise dimensions such as small steel sections and thin plates. Hot rolled By definition, steel ingots or billets are difficult to deform and process at room temperature. They are generally heated to 1100 to 1250°C for rolling. This rolling process is called hot rolling. The termination temperature of hot rolling is generally 800 to 900°C, and is generally cooled in the air afterwards, so the hot rolling state is equivalent to normalizing treatment. Most steel products are rolled using hot rolling methods. Steel delivered in a hot-rolled state has a layer of iron oxide scale formed on its surface due to the high temperature, so it has a certain degree of corrosion resistance and can be stored in the open air. However, this layer of iron oxide scale also makes the surface of hot-rolled steel rough and the dimensions fluctuate greatly. Therefore, steel with smooth surface, precise dimensions and good mechanical properties must...

Performance feature of 3CR12 and application introduction of 3CR12 stainless steel
European standard EN1.4003 China GB T 3280-2007: 00Cr12 Taigang T4003 3CR12 is a new type of weldable low-carbon ferritic stainless steel developed by the Columbus Plant in South Africa in the 1980s. The main feature of the product is to ensure a certain degree of wear resistance under humid environmental conditions. The welding performance of thicker products is improved, but the surface finish and color processing are difficult. Due to the rich mineral resources in South Africa, this steel type is very suitable for underground hot and humid environments. It is used to make funnels and chains for mines and mine equipment. This product is used to make power transmission and transformation towers in coastal areas. The service life can be extended to more than 20 years. It can also be made. Structural parts of the bridge, but the surface is preferably painted. 3CR12 is often used to replace coated carbon steel, weathering steel and aluminum. Offers the advantages of ferritic stainless steel such as strength, corrosion and wear resistance, weldable, formable, very durable, allowing for lower maintenance. The initial application field of 3CR12 stainless steel was in the corrosion/friction environment and was limited to the processing and manufacturing of...
