The main highlights of ST12, DC13, ST14 and ST15 steel strip products are as follows:
ST12: ST12 is a common cold-rolled steel with good stamping and drawing properties. It is usually used to make stamping or drawing parts. Its chemical composition includes carbon (C) ≤ 0.10%, manganese (Mn) ≤ 0.50%, phosphorus (P) ≤ 0.035%, sulfur (S) ≤ 0.035%, and contains a certain amount of aluminum (Alta ≥ 0.020%). The mechanical properties of ST12 include yield strength ≤ 280MPa, tensile strength ≤ 270 ~ 410MPa, elongation after fracture (L0 = 80mm, b = 20mm) ≥ 28%.
ST13: ST13 is a high-carbon high-chromium alloy tool steel with excellent wear resistance and hardness. It is often used to make various molds, knives and wear-resistant parts. The typical chemical composition of DC13 includes carbon (C) 1.50%, chromium (Cr) 12.00%, silicon (Si) ≤ 0.40%, manganese (Mn) ≤ 0.40%, phosphorus (P) ≤ 0.030%, sulfur (S) ≤ 0.030%. Due to its high hardness and good hardenability, DC13 can obtain high surface hardness and core hardness after proper heat treatment.
ST14: ST14 is a deep drawing grade cold rolled steel with better formability and higher strength. It is suitable for manufacturing parts that require deep drawing, such as automotive covers and household appliance housings. The chemical composition of ST14 is similar to ST12, but may contain more manganese or other elements to improve its strength and ductility.
ST15: ST15 is a low carbon ultra-deep drawing grade cold rolled steel with excellent stamping performance and surface quality. It is suitable for manufacturing high-quality deep drawing parts such as automotive fuel tanks and cans. The chemical composition of ST15 is further optimized to reduce impurity content and improve purity, thereby achieving better toughness and ductility.
In summary, these steel strip products each have their own unique advantages and are suitable for different industrial applications. The selection of the appropriate steel strip product needs to be based on specific usage requirements and performance requirements.
