Whether Q235NH alloy steel sheet need preheating

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has Q235NH alloy steel sheet strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and Q235NH alloy steel sheet pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

Among the most notable benefits of 304H stainless steel’s increased carbon content is its greater resilience in high temperature environments. It also benefits from good workability, lending 304H grades to key structural applications requiring high-strength plates and parts for complex or challenging features. This durability is guaranteed over the long term even when applied in severe processing/storage environments like boilers and pressure vessels Q235NH alloy steel sheet, due to the superb creep resistance of 304H stainless in both the short and long term.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe Q235NH alloy steel sheet is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick Q235NH alloy steel sheet steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

13CrMo4-5 seamless pipe is a kind of pressure resistant seamless pipe in accordance with the European standard EN 10216-2. The chemical composition of 13CrMo4-5 seamless pipe is C 0.10-0.17, Si ≤ 0.35, Mn 0.40-0.70, P ≤ 0.025, S ≤ 0.020, Cr 0.70-1.15, Ni ≤ 0.30, Mo 0.40-0.60, Al ≤ 0.04, Cu ≤ 0.03. Mechanical properties of 13CrMo4-5 seamless pipe: tensile strength: 440-590 MPa, yield strength: ≥ 290 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. Q235NH alloy steel sheet, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
