a516 grade 70 bar material vs stainless steel

The company has allocated special environmental protection facilities for all a516 grade 70 bar pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, a516 grade 70 bar steel mill scale, environmental protection dust has reached 100%.

The specifications available for a516 grade 70 bar, pressure vessel plates are: thickness 8-700mm, width 1500-4200mm, length 4000-17000mm, and unit weight up to 30.00 tons. Our company can provide cutting, welding, drilling and turning services if required. Available flaw detection requirements: Z15-Z35 thickness direction performance requirements, high strength and toughness requirements, pressure vessel plate and other steel plates.

Alloy steel seamless pipe is a kind of high-quality seamless steel pipe with outstanding performance and characteristics. The alloy steel seamless pipe has excellent high-pressure resistance and can withstand greater pressure. Even under pressure, the a516 grade 70 bar, alloy steel seamless pipe is not easy to break, and it is more safe and reliable to use. It also reduces the loss of pipe material and reduces the maintenance work of pipeline.

Nickel element is mainly used to form and stabilize the austenite structure, so that the a516 grade 70 bar steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

As for Q460 series low alloy steel, there are three quality Grade C, D, E. a516 grade 70 bar, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
