347H Stainless Steel Bar, Hot-Rolled, Forged, Polished, Cold Drawn, Corrosion-Resistant Round Bar
Introduction to 347h Stainless Steel:
347 stainless steel is a stable stainless steel with excellent resistance to intergranular corrosion and good high-temperature creep and stress fracture performance.
chemical composition:
The chemical composition of 347H stainless steel mainly includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), molybdenum (Mo), titanium (Ti), etc.
| C | Si | Mn | P | S | Cr | Ni | Mo | Ti | |
| content | 0.04~0.10% | ≤1.00% | ≤2.00% | ≤0.045% | ≤0.03% | 17.0~20.0% | 9.0~13.0% | ≤0.75% | 0.30~0.60% |
In addition, 347H stainless steel also contains other trace elements, such as niobium (Nb), with a content ranging from 8C to 1.10%. These chemical components endow 347H stainless steel with excellent corrosion resistance, welding performance, and thermal strength, making it suitable for high temperature, high pressure, and corrosive environments such as large boiler superheaters, reheaters, steam pipelines, and petrochemical heat exchanger fittings.
advantage:
1.Corrosion resistance: 347H alloy contains a high proportion of chromium and nickel, which can provide excellent corrosion resistance, especially against the corrosion of chloride ions. This makes 347H alloy suitable for use in highly corrosive environments in fields such as seawater treatment, chemical engineering, and petroleum.
3.High strength: By adding titanium element to form stable carbides, the creep resistance and high-temperature strength are improved. In addition, adding molybdenum can improve the tensile strength and hardness of the alloy, making 347H alloy suitable for high temperature, high pressure, and high load applications such as oil pipelines, nuclear power plants, etc.
4.High conductivity: 347H alloy has excellent conductivity and can be used in fields such as electronics, electrical appliances, and communication. Its conductivity is not affected by high temperature environments, so it is also suitable for the field of high-temperature electronics.
In summary 347H material has a wide range of application value in the industrial field due to its excellent corrosion resistance, high strength, and high conductivity.
