ASTM A335 Grade P22 Alloy Steel P22 Round P22 Bar

Product Description

Technical Overview

ASTM A335 P22 is a seamless ferritic alloy-steel, often referred to as "2-1/4 Chrome" steel. It contains $2.25\%$ Chromium and $1\%$ Molybdenum, providing exceptional high-temperature strength and better corrosion resistance than the P11 and P12 grades.

Key Specifications & Properties

Common Applications

P22 round bars are heavy-duty components used in critical high-heat environments:

• Power Plants: Main steam piping, boiler tubes, and headers.

• Oil & Gas Refineries: High-temperature processing units and distillation equipment.

• Chemical Processing: Reactors and heat exchangers dealing with corrosive fluids.

• Nuclear Industry: Structural components requiring high creep resistance.

Features to Highlight in Your Listing

• Excellent Creep-Rupture Strength: Specifically designed to withstand long-term stress at temperatures up to 600C.

• High Oxidation Resistance: The Chromium content ensures the steel does not scale or degrade in high-temperature steam.

• Hydrogen Service Reliability: Resists hydrogen embrittlement, making it safer for refinery use.

• Superior Finish: Available in Black,Bright,Polished, or Rough Turned finishes.
