Influence of chemical composition on A335 steel pipe

2020-12-14 09:04:16

Because A335 steel pipe contains the chemical composition of molybdenum and chromium, chromium-molybdenum steel pipe is often used. A335 steel pipe ordered according to this specification shall be suitable for bending, flanging and similar forming operations, as well as relief welding. Molybdenum can improve the strength of A335 steel pipe and improve the elastic limit, wear resistance, impact resistance and hardenability of A335 steel pipe.

Molybdenum increases the resistance to softening, strengthens the growth of grains, and makes chromium steel less susceptible to corrosion and embrittlement. Molybdenum is the most effective single additive force to increase high temperature creep. It also improves the corrosion resistance of A335 steel pipe and inhibits pitting corrosion.

Chrome is the basic component of stainless steel. Any A335 steel pipe containing 12% or more of chromium can be considered. Stainless steel chromium plating is almost irreplaceable in terms of high temperature oxidation resistance.

A335 steel pipe is an ideal material for conveying fluid and gas under extremely high temperature and pressure in power plants, oil refineries, petrochemical plants and oil fields.
