More professional S275J2 carbon steel plate sheet steel supplier

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of S275J2 carbon steel plate sheet etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in S275J2 carbon steel plate sheet etc. steel is strictly controlled.

Mechanical properties of S420NL-Z35 steel plate: yield strength≥235Mpa, tensile strength 360-510Mpa, elongation≥26%. The properties of S275J2 carbon steel plate sheet, S420NL-Z35 steel plate determine its application. S420NL-Z35 steel plate has high strength and good welding performance, which is commonly used in the manufacturing of mining machinery, engineering machinery, coal mine hydraulic support and other equipment and structural parts.

Steel transportation because of the special material of S275J2 carbon steel plate sheet steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

According to different purposes, the thin steel sheets are rolled from billets of different materials. Commonly used materials include plain carbon steel, such as S275J2 carbon steel plate sheet, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, and silicon steel for electrical purposes. The thin steel sheets are mainly used in the automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to delivery directly after rolling, there are also pickled, galvanized and tinned thin steel sheets.
