High Temperature Low Alloy Steel Bar
Diameter: 8mm - 350mm
Grade: T91/ P91/ T22/ P22
Yield strength(MPA): ≥ 415
Shanghai Metal Corporation is a professional manufacturer and supplier of High Temperature Low Alloy Steel Bar with high quality and reasonable price.
High temperature low alloy steel bar is a low alloy steel with high temperature strength and high heat resistance. It improves its performance by adding elements such as chromium (Cr), molybdenum (Mo), vanadium (V), nitrogen (N), and niobium (Nb) to the steel. The addition of chromium and molybdenum provides excellent oxidation and corrosion resistance; The combination of vanadium and nitrogen significantly improves the strength and toughness of the material. Mainly used in the manufacturing of supercritical and ultra supercritical steam boilers, turbine blades, nuclear reactor components, and other mechanical components that require high temperature and high pressure resistance in industries such as power, chemical, and petroleum.

Notes of High Temperature Low Alloy Steel Bar:
1. Choose appropriate stainless steel bars: Different stainless steel bars have different materials, specifications, and uses, and the appropriate materials and specifications should be selected according to the specific situation.
2. Pay attention to surface protection: The surface of stainless steel bars is prone to contamination and oxidation, and protective measures should be taken before use, such as using protective films, spraying anti-corrosion coatings, etc.
3. Pay attention to processing technology: The processing technology of stainless steel bars is relatively complex, and it is necessary to control parameters such as temperature and cutting speed during the processing to avoid material deformation or affect performance.
4. Pay attention to storage methods: Stainless steel bars should be stored in a dry, ventilated, and non corrosive gas warehouse to avoid moisture, corrosion, etc.
