Alloy steel pipe & tube
The benefits of alloy steel pipe include its tensile strength, yield strength, fatigue resistance, toughness, and wear resistance.
A333-6 low temperature steel pipe welding
A333-6 steel is a low-temperature steel. The minimum temperature of 70 ° C. Usually normalized or normalized and tempered state supplier.
A333-6 steel carbon content is lower, so hardened the tendency and cold cracking tendency are relatively small. Material toughness and ductility is better, generally difficult to produce hardening and cracks, good weldability, optional W707Ni electrode with El the imports of wire TGS 1N, using argon ITU welding. To ensure good toughness of welded joints.
A333-6 Chemical composition
| C | Mn | Si | S | P |
| ≤0.120 | 0.290-1.060 | ≥0.100 | ≤0.058 | ≤0.048 |
A333-6 Mechanical property
| tensile strength(Mpa) | yield strength(Mpa) | elongation(%) |
| 414 | 241 | ≥16.5 |
Preheat
When the ambient temperature is below 5 ° C required weldment preheating. Preheat temperature of 100-150 oC: Preheat the scope of welds on each side of 100 mm; heating oxyacetylene flame (neutral flame) temperature measuring pen measuring the temperature at 50 ~ 100 mm from the center of the weld. The measurement points uniformly distributed, in order to better control the temperature.
