St44-3 High Strength Low Alloy Plate
St44-3 hsla steel plate belongs to the German standard low alloy high strength structural steel plate. The implementation standard of St44-3 high strength low alloy steel plate is the special technical conditions of DIN 17100-1980.
St44-3 high strength alloy steel itself has high-quality properties such as high strength, high toughness, impact resistance, wear resistance, corrosion resistance, welding and easy processing. Therefore, St44-3 high strength steel is widely used in equipment in a variety of industries due to its multiple high-quality properties.
