Equivalent material and performance of ST44-2 steel plate

ST44-2 steel plate is a German standard, and the corresponding Chinese GB standard is Q255A or Q255B material. ST44-2 steel plate belongs to carbon structural steel, which has quite high strength and good welding performance. It can be used to manufacture mechanical parts that do not require high strength, such as rockers, tie rods, mandrels, shafts, bolts, keys, and steel structures. Various profiles and steel plates.

Chemical composition of ST44-2 steel plate: Carbon C: ≤0.21St44-2 Manganese Mn: ≤1.50St44-2 Phosphorus P: ≤0.035St44-2 Sulfur S: ≤0.035St44-2 Copper Cu: ≤0.55St44-2 Nitrogen N: ≤0.012V> Yield strength of ST44-2 steel plate (σ0.2/MPa): ≥275 Elongation δ (%): ≥23

Description of ST44-2 steel plate: Suitable for molds and parts with complex shapes and precision; excellent cutting performance, easy to process and mold; it is expected to shorten the mold processing cycle and reduce costs; if the surface treatment is applied, the ST44-2 steel plate can be further improved Wear and corrosion resistance.
