High chromium cast iron pipes

High chromium cast iron pipe is an alloy steel intended for high temperature and high pressure services.

High chromium cast iron pipes

Features of High chromium cast iron pipes:

The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. The rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%.

Chrome-Moly
  • Chromium-Molybdenum Alloy Steel or Chrome-Moly, CrMo is an alloy steel intended for high temperature and high pressure services.
  • Chrome-Moly is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength.
  • Chrome-Moly has a better strength to Weight ratio than steel, which enables designers to use thinner wall pipe or smaller diameter tubing to reduce overall weight.
  • Chromium-Molybdenum Alloy Steel has strong resistance to rupturing at high temperatures and high pressures.
  • Chrome-Moly is also resistant to cracking from hydrogen attack and hot sulfide corrosion cracking.
  • Chrome-Moly grades P-11, P-22, P-91 and P-92 are used in the power industry.
  • Chrome-Moly grades P-5 and P-9 are used in petro-chemical refinery processes.
  • Chrome-Moly Forged Fittings & Flanges are available in grades F-5, F-9, F-11, F-22, F-91, F92.
  • Chrome-Moly Alloy Butt Weld Fittings are available in grades WP-5, WP-9, WP-11, WP-22, SP-91, WP-92.
  • F11 and F22 meet NACE-MRO 175.

Performance indicators:

  • Grade: ZG40CrNiMoMnSiRe
  • Hardness: HRC ≥ 40
  • Impact toughness: ≥ 14J/cm2
  • Tensile strength: ≥ 700MPa

Uses:

Rare high-strength low-alloy heat-resistant, wear-resistant steel parts for the power plant boiler systems in coal, powder, ash slagging pipeline.

Packing:

  • Packed in wooden crates, wrapped in plastic, and suitably protected for sea-worthly delivery or as requested.
  • Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles.

We have a team of experienced professionals with years of experience in manufacturing.
