The weldability of TMCP ABS E36 hull steel plate

Based on the advantages of TMCP ABS E36 hull steel plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel TMCP ABS E36 hull steel plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions; Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel TMCP ABS E36 hull steel plate is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.

The advantages of TMCP ABS E36 hull steel plate, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized TMCP ABS E36 hull steel plate are higher than that of annealed TMCP ABS E36 hull steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of TMCP ABS E36 hull steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.

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. TMCP ABS E36 hull steel plate, 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).

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
