20CrMo is an alloy structural steel containing alloy elements such as chromium (Cr) and molybdenum (Mo). Chromium can enhance the steel's oxidation resistance and corrosion resistance, while molybdenum improves its mechanical properties at high temperatures. This steel has higher strength and hardenability than carbon steel, good plasticity and toughness, good weldability, medium plasticity during cold deformation, and good cutting performance.
It has excellent strength, toughness and wear resistance, high hardenability, no temper brittleness, good weldability, little tendency to form cold cracks, good machinability and cold strain plasticity. Tensile strength σb (MPa) ≥ 885 (90), elongation δ5 (%) ≥ 12, cross-sectional shrinkage ψ (%) ≥ 50, impact energy Akv (J) ≥ 35, impact toughness value αkv (J/cm²) ≥ 98 (10), hardness ≤ 212HB
Galvanized angle steel is a specific type of galvanized steel. Galvanized steel is a steel material that has been galvanized. Galvanizing is a technology that coats the surface of steel with a layer of zinc. This layer of zinc can prevent the steel material from corrosion.
SS400 is a steel grade specified in the Japanese JIS standard, where SS stands for structural steel and 400 means its minimum tensile strength is 400MPa. Its main chemical components include carbon (C), silicon (Si), manganese (Mn), sulfur (S) and phosphorus (P). The carbon content is about 0.05-0.20%, the manganese content is about 1.40-1.75%, and it also contains a small amount of impurity elements such as sulfur and phosphorus. For SS400 angle steel, its chemical composition should comply with the provisions of JIS G3112, with a carbon content between 0.18%-0.28%, a silicon content between 0.12%-0.30%, a manganese content between 0.70%-1.00%, and a certain amount of phosphorus (P) and sulfur (S) elements to increase hardness and strength.
High precision: Cold rolled steel plates have more precise thickness and high dimensional accuracy, which can meet the needs of various precision machining. Superior performance: It has good mechanical properties such as high strength and hardness, as well as a certain degree of toughness, which can meet the requirements of different application scenarios.
Cold rolled carbon steel strip has become a key basic material in the high-end manufacturing field due to its core advantages of high precision, excellent surface quality, adjustable performance, and flexible processing. Its characteristics are highly adaptable to the needs of automated production and precision machining, and are irreplaceable in industries such as automotive, electronics, and home appliances.
