What is the hardness of a242 type 1 cold rolled weathering steel coil

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, a242 type 1 cold rolled weathering steel coil and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

Special boiler steel is derived from carbon structural steel, a242 type 1 cold rolled weathering steel coil. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

There are various weather resistant steel materials in the world. Their thickness ranges are distinct. For JIS G3125 weathering steel sheet, typical grades are SPA-H / SPA-C, the max. thickness is 16mm. For TBT 1979 weather resistant steel sheets, typical grades are 09CuPCrNi-A / 05CuPCrNi, the max. thickness is 20mm. For EN 10025-5 steel, typical grades are S355J0WP / S355J2WP / S355J0W /S355J2W, the max. thickness is 100mm. The max. thickness for a242 type 1 cold rolled weathering steel coil, ASTM A588 steel plate is 200mm. And the max. thickness for ASTM A242 steel plate is 100mm.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
