The difference between laser cutting for S420N carbon steel material and stainless steel

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

SA299GrB steel plates with a thickness of less than or equal to 50mm are usually delivered in the rolled state, and can also be delivered in the state of normalizing, stress relief, or normalizing plus stress relief. Steel plates with a thickness greater than 50mm should be normalized heat treatment. It can also add flaw detection standard requirements, flaw detection level requirements, alloy element composition control requirements, etc. according to needs.

The cold working performance of S420N carbon steel material and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of S420N carbon steel material and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched S420N carbon steel material increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S420N carbon steel material during tempering, while tempering determines the performance and life of the workpiece.

We are professional S420N carbon steel material carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world. If you have any question about carbon steel materials, such as A36 steel modulus of elasticity, A283 grade C properties, A572 grade 50 hardness, S420N carbon steel material EN 10025 S235JR equivalent Indian standard, S355JR specification, carbon steel price etc., please feel free to consult us.

Company management philosophy: integrity-based, service-oriented, excellence, affinity symbiosis. Based on quality, continuously create maximum value for customers. Always have a grateful heart, thank the society, thank family and friends for their support and help to the development of the company, thank customers for their trust, thank colleagues for their cooperation, and thank competitors for their supervision.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
