Manufacturer material hardox 400 steel lift gate steel

ASTM A36 and JIS G3192 steel angle material HARDOX 400 steel is one of the most widely used carbon steel section in the construction industry and project. It is a low-cost material and shows the required strength property compared with other steels. It is popular also for its good weld performance, formable, and easy material HARDOX 400 steel machining. Galvanizing and other treatment increases its resistance to corrosive environment.

We are world class steel material HARDOX 400 steel materials supplier. We are engaed in providing raw steel materials such as steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for material HARDOX 400 steel quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build long-term cooperation with you.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < material HARDOX 400 steel steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished material HARDOX 400 steel product packaging.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the material HARDOX 400 steel, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
