What are the precautions during the cutting of EN 10155 equivalent materials

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products EN 10155 equivalent materials are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The EN 10155 equivalent materials, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
