Heat Resistant Steel plate

Abrasion resistant (AR) steel plate is a high-carbon alloy steel plate. This means that AR is harder due to the addition of carbon, and formable and weather resistant due to added alloys.

Such steel is generally used in applications where resistance to increased temperatures are critical. The steel is hard wearing and offers a resistance to large variations in temperature. Industrial applications include furnaces, heat exchanges and incinerators where temperatures can reach in excess of 1100°C.

Characteristics include corrosive resistance, creep resistance, oxidation resistance and hydrogen brittleness – all under extremely high temperatures. Our steels are made from nickel and titanium based alloys for outstanding high temperature performance.

Carbon added during the formation of the steel plate substantially increases toughness and hardness, but reduces strength. Therefore, AR plate is used in applications where abrasions and wear and tear are the main causes of failure, such as industrial manufacturing, mining, construction and material handling. AR plate is not ideal for structural construction uses like support beams in bridges or buildings.

Some common applications where AR steel is used to help resist material wear and tear include:

  • Conveyors
  • Buckets
  • Dump liners
  • Construction attachments, such as those used on bulldozers and excavators
  • Grates
  • Chutes
  • Hoppers

Applications of Heat Resistant Steel

For most types of steel, the desirable properties and yield strength lessen significantly as the steel is exposed to high temperatures. heat resistant steels are resistant to temperatures over 500°C, maintaining their strength and other properties. Here we will outline the basics of heat resistant steels and their key applications.

How is Heat Resistant Steel Made?

Heat resistant steel is strengthened using alloys, heat treatment, solid solution, and precipitation. Chromium is present in all types of heat resistant steel, offering oxidation resistance, high-temperature strength, and carburization resistance. Chromium makes heat resistant steel ferritic.

Nickel is sometimes added to heat resistant steel to enhance ductility, temperature strength, and carburizing and nitriding resistance. Nickel makes the atomic structure of steel austenitic. Carbon can also be added to steel as a strengthening element, dissolving in alloy and enhancing solution strength.

Heat Resistant Steel for the Oil and Gas Industry

Steel is a critical material in the oil and gas industry, used in every part of the industry from the marketplace to transportation, to construction. The demands put on heat resistant steel in these industries are extremely high, meaning they must go under stringent testing and come from reputable steel mills that are high quality.

Some of the applications in the oil and gas industry can lead to structural or thermal stresses, crack growth, fatigue, and corrosion which must be frequently inspected and maintained. Applications in the oil and gas industry require extremely high temperatures which can make standard steel brittle.

Why Furnaces Use Heat Resistant Steel

Industrial furnaces are used for smelting at high temperatures, tempering, drying, and heat treatment. Industrial furnaces can sometimes require temperatures of up to 3000°C, meaning standard steel would be adversely impacted by the high temperatures required.

In furnace applications, the exposure to heat will be intermittent rather than prolonged. Heat resistant steel can tolerate frequent exposure to high temperatures in short stretches as well as over long periods.

About Chrome Moly

Chrome Moly is one of our most popular heat resistant steels and is commonly found throughout the oil, gas and petrochemical industries. The combination of chromium (giving the steel excellent corrosion resistance) and Molybdenum (for greater tensile strength and heat resistance), makes this steel an ideal choice for high temperature working environments.

Chrome Moly is a widely used heat resistant steel that is used in petrochemical, oil, and gas industries. The mixture of chromium for corrosion resistance and molybdenum for increased tensile strength means it is well suited to environments that require extremely high temperatures.

Chrome Moly also has an excellent strength-to-weight ratio, making it easier and more cost-effective to install and manage than many other heat resistant materials.
