Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). S355M structural steel grade. Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
Our company produces ordinary carbon steel S355M structural steel grade with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a S355M structural steel grade production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.
The purpose of S355M structural steel grade quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of S355M structural steel grade. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For S355M structural steel grade ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the S355M structural steel grade standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
