Product Description
st35.8 steel pipe NBK GBK cold drawing carbon pipes

Standard:DIN 17175 : Seamless Steel Tubes For Elevated Temperatures

As far as DIN 17175 is concerned, steels that have a good mechanical properties at a higher temperature, up to 6 00 °C, and even under long-term load, are called heat-strength steels.

DIN 17175 St35.8 Seamless Steel Tubes can be used to manufacture steam boilers, pipes, pressure vessels and instruments operating at temperatures up to 600 ° C and at high temperatures.

ST35.8 STEEL PIPE DELIVERY CONDITION


1. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee
4. BKW(+LC)
after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)
5. BKS(+SR)
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again

 

 

ST35.8 STEEL PIPE SUPPLY STATUS 
The 17175 St35.8 Seamless Steel Tubes Will be delivered through a suitable heat treatment. heat treatment includes:
- Normalizing
- Annealing
- Tempering; from the quenching temperature, it is not cold, but then tempered
- Adjust the mass by the isothermal transformation method.

 

Original material test
A thin sheet should be taken at the top end of each round or square bar ingot for a pickling test to determine if the top end is adequately cut. Ultrasonic testing can also be performed on the shrinkage hole as selected by the supplier.

Test:
- Chemical composition verification test
- hydrostatictest
- Tensile test
- Notched impact test
- Yield strength test
- Ring test
- Nondestructive testing
