A514 Gr M alloy steel plate,Our company was founded in 2000, which initially committed to providing high-quality steel products for China's rapid infrastructure construction With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export steel to the international market, opening up the international steel market,A514 Gr M alloy steel plate.
A514 Gr M alloy steel plate, and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate Therefore, the medium and heavy plates manufacturers and users attach great importance to it The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc, which is one of the main quality indexes of medium and heavy plates,A514 Gr M alloy steel plate.
45# steel is commonly used medium carbon quenched and tempered structural steel. The steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained 45# steel normalizing can improve the cutting performance of roughness less than 160HBS,A514 Gr M alloy steel plate.
A514 Gr M alloy steel plate,Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).
A514 Gr M alloy steel plate,We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
