LOW TEMPERATURE STEEL PIPE

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.
