Welcome to BBN High Strength Steels Factory
The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.
The company manages NM400 wear-resistant plate, NM450 wear-resistant plate, S690QL1 steel equivalent, NM500 wear-resistant plate and other wear-resistant plate products. The wear-resistant plates are widely used in many industries, such as engineering, mining, cement, power, construction, machinery, coal, glass manufacturing, paper making, metallurgy, petrochemical, etc.. And the wear-resistant plates are also used in wheel device, grab equipment, bucket body, edge, lining plate, hopper, funnel, bucket valve, etc. parts.
Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. S690QL1 steel equivalent, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the S690QL1 steel equivalent steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
S690QL1 steel equivalent, A572 Grade 50 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the A572 Grade 50 steel coil thickness should not exceed 25 mm. For A572 Grade 50 steel, the C element content is 0.23%, the Si element content is 0.4% max, the Mn element content is 1.35% max, the P element content is 0.004% max, the S element content is 0.05% max, the V element content is 0.06%, the Ni element content is 0.015%, the Co element content is 0.05%.
When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
