Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for ASTM A572 high strength steel various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several ASTM A572 high strength steel after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
Boiler steel plates are mainly used to manufacture various boilers and important accessories. Because the boiler steel plate is working under medium temperature (below 350°C) and high pressure, in addition to high pressure, it is also subject to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength and also have good welding and cold bending performance. Common grades: Q245R, A515 Grade 55, A515 Grade 60, ASTM A572 high strength steel, A516 Grade 65, A516 Grade 70.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. ASTM A572 high strength 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 wear-resistant plate ASTM A572 high strength steel shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and ASTM A572 high strength steel hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel ASTM A572 high strength steel products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the ASTM A572 high strength steel customer's requirements and meet the customer's requirements.
