Alloy round steel has high chromium content, which is beneficial to wet corrosion resistance, as well as improving its high temperature strength and high temperature scaling resistance.

The key to the P5 composition of chromium-molybdenum alloys is the addition of chromium and molybdenum. Chromium or chromium increases high temperature strength, increases oxidation resistance and increases tensile, yield and hardness at room temperature. Molybdenum improves strength, elastic limit, wear resistance, impact quality and hardenability. It increases resistance to softening, inhibits grain growth, and makes chrome steel less susceptible to embrittlement. Molybdenum is also the most effective additive for increasing high temperature creep strength or creep resistance. It also enhances the corrosion resistance of the steel and inhibits pitting corrosion.

Alloy steels are used in a range of demanding applications in the aerospace and power (nuclear) industries. Adding other elements gives alloy steel extra strength.

Chrome alloy steel flanges are manufactured in accordance with ASTM A182 F11/F12 and are widely used in nuclear power plants, power plants, water systems, electric power, oil fields, pipeline engineering, natural gas, marine engineering, shipbuilding and other industries. These flanges are harder and stronger than regular steel, but not as corrosion resistant as stainless steel.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

Alloy steel pipes and tubing are the best choice for stress corrosion cracking (SSC). These also apply to environments where the problem is pitting and crevice corrosion. These tubes and tubes are available within machining allowances and tolerances.

ASTM 182 is used for pressure systems, including fittings, flanges,and similar parts that conform to specified dimensions or dimensional standards such as ASME codes.

Chromium and molybdenum are high in A335 pipes. While molybdenum improves overall strength, resistance, elasticity, hardenability and overall quality, molybdenum ensures that the material is more resistant to softening, inhibits grain growth and reduces the chance of embrittlement. It is the only additive that improves the high temperature resistance and also improves the corrosion resistance of the steel.
