What is hardox 450 steel hardness ASTM equivalent

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

Heat-resistant steel thick plate is made of heat-resistant steel and is processed by hot rolling. According to different structure characteristics, it can be divided into four types: austenitic type, ferrite type, martensite type and precipitation hardening type. Hardox 450 steel hardness, The heat-resistant steel plate is widely used in the manufacture of petroleum, chemical equipment, boilers, steam turbines, industrial furnaces and other components and other components working at high temperatures.

ASTM A333 Grade 6 pipe Hardox 450 steel hardness for low temperature services at above -45℃.Pipe Sizes: 1/8” to 24”Wall thickness Schedules: SCH 10, SCH 20, SCH 40, SCH STD, SCH 80, SCH XS to SCH 160, SCH XXSLength: Single Random Length, Double Random Length, 20 ft, 40 ftEnds Types: Plain, BeveledCoatings: 3PE/3LPE, FBE, Galvanized, Varnished, CRA or stainless clad and lined

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they Hardox 450 steel hardness work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
