Large stock EN steel grade S420NL material from China factory

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel EN steel grade S420NL material products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the EN steel grade S420NL material market and has strong competitiveness.

Q960 quenched and tempered steel grade classification: Q960C, Q960D, Q960E, Q960F. The product EN steel grade S420NL material thickness is not more than 150MM. Q960 quenched and tempered steel has high yield strength and tensile strength, and its resistance to brittle failure is also great. Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.

Compared with EN steel grade S420NL material, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while EN steel grade S420NL material is not.

EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as EN steel grade S420NL material high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging cold

The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The EN steel grade S420NL material, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
