Carbon Steel

AISI 4140 steel bar is composed of a low alloy steel featuring chromium, molybdenum, and manganese. With a high carbon content, it offers a favorable balance of strength, toughness, wear resistance, impact resistance, and heat treatment capabilities.

AISI 4340 carbon steel bar is crafted from a heat-treatable low alloy steel comprising chromium, nickel, and molybdenum. It offers high toughness and strength under heat treatment conditions.

The 5160 steel bar is composed of a medium-carbon alloy steel, featuring specific components such as carbon, chromium, manganese, silicon, phosphorus, and other elements. Additionally, 5160 steel includes a small amount of chromium to enhance its hardenability.

The 8620 steel bar is a type of low alloy steel primarily comprised of iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, and other elements. It exhibits good hardenability and weldability, and can achieve exceptional mechanical properties through heat treatment.

The A53 American standard seamless steel pipe is manufactured from high-quality steel billets using processes such as hot rolling, cold drawing, and others. The chemical composition and mechanical properties of this steel pipe adhere to the specifications outlined in the American standard ASTM A53/A53M.

ASTM A106 grade seamless steel pipe is extensively utilized as a low carbon steel in the petroleum, chemical, and boiler industries. This material is known for its favorable mechanical properties and finds widespread application in various industrial settings.

The A179 seamless cold drawn low carbon steel pipe is comparable to China’s No. 10 high-quality low-carbon steel. A179 is well-suited for cold-drawn, high-quality, low-carbon seamless steel pipes used in heat exchangers and condensers.

ASTM A192, also known as ASME SA-192, is the standard specification that encompasses seamless carbon steel boiler and superheater tubes with minimum wall thickness for high-pressure service.

A213 is a seamless steel pipe made of ferritic and austenitic alloy, designed for use in boilers, superheaters, and heat exchangers. Its products are required to adhere to the TSG D7002 pressure piping component type test regulations.

ASTM A252 serves as the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder functions as a permanent load-bearing member or shell to create a cast-in-place concrete pile. The ASTM A252 specification encompasses three grades: Grade 1, Grade 2, and Grade 3, with Grade 2 and Grade 3 being commonly.

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipes designed for low-temperature applications or other applications necessitating notch toughness. This standard encompasses various grades of ferritic steel, including Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10, and Grade 11.

The ASTM A335 steel pipe may undergo hot finishing or cold drawing and is then subjected to the following finishing heat treatment. This specification encompasses seamless pipes made of “chrome-molybdenum” with outstanding corrosion resistance and high-temperature tensile strength.
