For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of A573 gr 58 BV certificate smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. A573 gr 58 BV certificate, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.

It is a modern high-tech professional enterprise integrating scientific research, A573 gr 58 BV certificate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A573 gr 58 BV certificate process technology development, technology transfer and related technical consulting and technical services.
