Carbon Steel Suppliers From China

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contain a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.

• Low carbon steel, carbon content less than 0.25%.
• Medium carbon steel, carbon content is 0.25%-0.6%.
• High carbon steel with carbon content greater than 0.6%.

Low carbon steel (mild steel) is carbon steel with a carbon content of less than 0.25%. Because of its low strength, low hardness and softness, it is also called mild steel. Low carbon steel models are Q195, Q215, Q235, Q255 and Q275 etc.

Medium carbon steel has a carbon content between 0.25% and 0.60%, usually has moderate strength and toughness, and is a commonly used structural steel. Here are some common medium carbon steel grades:

45#: A general-purpose medium carbon steel with good weldability and mechanical properties, usually used to make mechanical parts and tools.

50#: Medium carbon steel, usually used to manufacture mechanical parts with higher strength, such as gears and bearings.

55#: Medium carbon steel, with excellent toughness and wear resistance, usually used to manufacture high-strength mechanical parts.

60#: Medium carbon steel, with high strength and hardness, usually used to manufacture wear-resistant and heat-resistant parts.

65Mn: A spring steel with high carbon content, suitable for making springs, saw blades, blades, etc.

In general, the steel grades of medium carbon steel are suitable for various mechanical and structural applications, have good mechanical properties and processability, and are widely used in industry and manufacturing.

High carbon steel is often called tool steel, with a carbon content ranging from 0.60% to 2.11%, and can be hardened and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drills, taps, reamers, etc. are made of steel with a carbon content of 0.90% to 1.00%. AISI 1055 – AISI 1095

Contains between 1.4% and 2.0% carbon and is used in applications such as knives, axles, and punches.

SK2: A Japanese ultra-high carbon tool steel with a carbon content between 1.10% and 1.30%. It has extremely high hardness and cutting performance. It is usually used to make knives, wire ropes, and springs.

SK5: A Japanese ultra-high carbon tool steel, with a carbon content between 0.80% and 0.90%, has high hardness and wear resistance, and is usually used to manufacture saw blades, knives, springs, and hammerheads.

T10: A Chinese ultra-high carbon tool steel with a carbon content between 1.00% and 1.10%, which has high hardness and strength, and is usually used to make knives, coolers, and grinding tools, etc.

C105U: A European ultra-high carbon tool steel with a carbon content between 1.05% and 1.20%. It has extremely high hardness and strength. It is usually used in the manufacture of saw blades, knives, and cutting tools.

In general, ultra-high carbon steel is extremely hard and strong, but also brittle, so heat treatment and other processes are often required to improve its toughness and machinability. The choice of steel grade depends on the specific application requirements, and different steel grades have different characteristics and scopes of application.
