Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, S420ML hardness. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.
S420ML hardness, API 5L X52 steel with the thickness range is 1.2-40mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. API 5L X52 steel’s mechanical properties is the yield strength 300MPa, and the tensile strength 460MPa. To be specified in details: Maximum content for C≤0.28%, Mn≤1.4%, P≤0.030%, S is 0.030%, V+Nb+Ti≤0.15%, Copper maximum is 0.50%, nickel maximum 0.50%, chromium 0.50%, Molybdenum 0.15%.
Pressure vessel plates S420ML hardness are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled S420ML hardness plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive S420ML hardness industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
