Material Description:

 

S31042 (25Cr-20Ni-Nb-N) is a new type of austenitic heat-resistant steel, which has been widely used in superheaters and reheaters of supercritical and ultrasupercritical boilers. The steel contains 25% Cr and 20% Ni, and the steam oxidation resistance and high temperature corrosion resistance are obviously better than the traditional 18% Cr heat resistant steel.

 

Size Range for tubing:

OD:1/4" (6.25mm) to 8" (203mm)

WT 0.02" (0.5mm) to 0.5"(12mm)

Length:15m(Max) or as your requirement

 

Process: 
Cold drawn, Cold rolled, Precision Rolled for Seamless Pipe or Tube
Gas tungsten arc welding, Plasma arc welding (PAW),Submerged arc welding (SAW) For Welded Pipe or Tube

Finish: Annealed & pickled, bright annealing, polished

Ends: Beveled or plain end, square cut, burr free ,Plastic Cap at Both end

Packing: Bare packing/bundle packing with woven bag/wooden or steel frame crate packing/plastic cap protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.

 

Inspection and Test Procedure
1. 100% PMI,Spectro Chemical Aanlysis Test for Raw Material
2. 100% Dimension & Visual Examination
3. Mechanical Properties Test Include Tension Test,Flaring Test (For Seamless tube/pipe)/ Flange Test (For Welded Pipe & Tube), Hardness Test ,Reversed Flattening Test
4. 100% Hydrostatic Test or 100% NON-DESTRUCTIVE Test (ET or UT)
5. Radiographic Test for Welded Pipe (shall be accordance with specification,or shall be as agreed upon between the purchaser and vendor)
6. Straightness Test (optional)
7. Roughness Test (optional)
8. Intergranular Corrosion Test(optional)
9. Impact Test (optional)
10. Grain Size Determinations (optional)
NOTES : ALL THE TESTS AND INSPECTION RESULT NEED TO BE SHOWED IN REPORTS ACCORDING TO STANDARD AND SPECIFICATION.
