Product Description

Product Description:

Carbon Steel Bar

The Carbon Steel Bar is a type of bar made from carbon steel , a popular material known for its strength and durability. This product is widely used in various industries such as construction, manufacturing, and automotive.

The color of carbon steel can vary depending on the type of finish applied. The most common colors for carbon steel bars are gray for steel and silver for stainless steel .

 

Our Carbon Steel Bar comes in different shapes and sizes, including carbon steel solid bar , mild carbon steel bar , low carbon steel bar , and high carbon steel bar . These bars can also be customized to meet the specific needs of our customers.

The length of our carbon steel bars can either be random or customized , depending on the requirements of the project. We also provide different types of carbon steel bars, such as round bar , square bar , flat bar , hexagonal bar , and triangular bar .

Our Carbon Steel Bar is classified under Hs Code 7213100000 , which is used for flat-rolled products of iron or non-alloy steel . This code is used for international trade and customs purposes, ensuring that our product meets the required standards and regulations.

1: 4130 steel introduction
AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum. It is similar to 4140 steel which has a higher carbon level (0.28-0.33%), giving 4130 material improved weldability, at the expense of through thickness strength. With the proper heat treatment it is also readily machined. Annealing ASTM 4130 alloy steel offers excellent ductility. AISI 4130 steel is usually supplied as round bar commonly in the hardened and tempered condition.
