Introduction of Q420E steel plate

Q420E belongs to low-alloy high-strength structural steel plate, and the implementation standard of Q420E steel plate is GB/T3274 special technical conditions or international, domestic and industry standards or according to the agreement.

Q420E steel plate itself not only has high strength, but also carries some comprehensive high-quality properties such as high toughness, fatigue resistance, impact resistance, wear resistance, low temperature resistance, corrosion resistance and easy welding and processing.

Delivery status of Q420E steel plate:
Q420E steel plate is delivered in a silent low temperature state, and can be normalized, tempered, controlled, and modulated according to different needs.

Q420E steel plate thickness flaw detection can be done 'NB1 detection, NB2 detection, NB3 detection' when necessary
Q420E steel plate thickness extension can be done 'z15, z25, z35'

The construction machinery steel produced by Q420E is mainly used in the manufacture of chassis parts of crawler construction machinery such as excavators, including chain rail links, rollers, pin bushings, crawler shoes and other four-wheel and belt products, as well as boom pin shafts , support parts, hydraulic parts and other products with steel. The ingredient control and purity have reached the domestic leading level, and the product performance is stable.
