Always check DIN 1.4373 Square and Rectangular Pipe thickness and weight before buying material

Like alloy 201, the toughness property of grade 202 stainless steel is better at lower temperatures. Generally, traditional stainless steels do not perform well at low temperatures, and unlike the Stainless Steel 202 Welded Pipe often exhibits failure by cracking. The alloy is referred to as a precipitation hardening grade by several 202 Stainless Steel Pipe Manufacturers. The main advantage of precipitation-hardened alloys is that they demonstrate an increase in the tensile strength of the steel.

In addition to having both high hardness, and high tensile strength, the ASTM A312 UNS S20200 ERW Pipe possesses properties such as good corrosion resistance and high toughness. The welding process of this alloy is possible by the use of common fusion and resistance techniques. Yet, most manufacturers caution against using the oxyacetylene welding method to manufacture the SS 202 Welded Pipe. Since the content of chromium in the alloy ranges between 17% to 19%, the ASME SA312 TP 202 Square Pipe can form a passivating oxide layer, thereby effectively exhibiting very good resistance to decay via oxidation.

Similar to grade 304, the content of Molybdenum in ASTM A358 tp 202 EFW pipe is lacking. However, the content of nickel in grade 304 is significantly higher than the SUS 202 schedule 40 pipe. Therefore, the cost of the economical austenitic stainless steel alloy 304 is astronomically higher than the grade DIN 1.4373 Rectangular Pipe.
