In terms of service, our service is a "one-stop" way of working. We have our own A709 Gr 50W low alloy steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as A709 Gr 50W low alloy steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.
A572-50 (A572 grade 50) plate has a higher yield and tensile strength than A36 plate, combined with a lower weight. This steel is a high strength, low alloy steel plate. It offers an optimum combination of strength, weldability and notch toughness. A709 Gr 50W low alloy steel Applications include: bridges, buildings, automotive and truck parts, railroad cars, cargo containers, tote boxes, construction equipment, structural tubing, lighting standards and transmission poles.
40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. A709 Gr 50W low alloy steel, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.
A709 Gr 50W low alloy steel, Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A709 Gr 50W low alloy steel, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
The high strength A709 Gr 50W low alloy steel low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you.
