Is the cutting method in A588 Grade B tempered and quenched steel cutting comparable

Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel A588 Grade B tempered and quenched steel and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

Can A588 Grade B tempered and quenched steel, 40Cr material be replaced with 40MnB steel? 40MnB steel is used to manufacture small and medium-sized important quenched and tempered parts in tractors, automobiles and other general machinery and equipment, such as automobile half shafts, steering shafts, spline shafts, worms and machine tool spindles, gear shafts, etc. 40MnB steel can replace 40Cr material to make parts with larger cross-sections, such as the middle shaft of a hoist. And 40MnB steel can replace 40CrNi steel when making small-sized parts.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the A588 Grade B tempered and quenched steel, alloy steel is very high, it is not easy to break and can be used for a long time.

The steel such as A588 Grade B tempered and quenched steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with A588 Grade B tempered and quenched steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

The company's products A588 Grade B tempered and quenched steel have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow. The needs and interests of users are our high philosophy of service and commitment, and customer satisfaction is our eternal pursuit.
