08X18H12B TP347H Stainless Steel Boiler Tube Cold Drawn Stainless Steel Seamless Pipe
Material
08X18H12B (identical to TP347H) is a austenitic widely applied in boiler tubes and seamless pipes. It consists of stabilized factors like niobium that enhance resistance to intergranular corrosion at stepped forward temperatures. The bloodless-drawn finishing gadget complements mechanical homes and floor finish, making it suitable for critical excessive-temperature packages.
Specification
- modern-day: GOST 8734-75, ASTM A213, ASTM A269, EN 10216-5
fabric Grade: 08X18H12B (GOST) / TP347H (ASTM)
shape: Seamless pipe and bloodless-drawn tube
Diameter range: commonly from 10 mm to 630 mm
Wall Thickness: Variable counting on software requirements
length: custom designed as in step with call for (commonly 6m or cut to duration)
Key Features
- wonderful excessive-temperature oxidation resistance
superior corrosion resistance in competitive boiler environments
high creep strength and accurate mechanical homes at prolonged temperatures
Stabilized with niobium (Nb) to save you sensitization and intergranular corrosion
bloodless drawn for extra advantageous tensile energy and smoother ground end
properly weldability and formability
