The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing ASTM A514 quenched and tempered steel high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of ASTM A514 quenched and tempered steel cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.
Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with ASTM A514 quenched and tempered steel ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
The basic principle of ASTM A514 quenched and tempered steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the ASTM A514 quenched and tempered steel raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, ASTM A514 quenched and tempered steel bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines. Welcome to come China and visit our ASTM A514 quenched and tempered steel production line.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
