McMaster-Carr

Also known as mild steel, multipurpose steel includes low-carbon grades, such as 1018 and A36. Easy to machine, form, and weld, it's widely fabricated into fixture clamps, mounting plates, spacers, and other parts that don’t require high strength.

Easy-to-Machine Carbon Steel

Carbon steel grades 12L14, 1215, 1144, and 1117 are formulated to ensure the best machining qualities. They're best for parts that don't require welding, such as shaft couplings and mandrels.

Wear-Resistant AR400 Carbon Steel

The nickel and molybdenum content gives AR400 carbon steel the ability to resist wear better than all other carbon steel. It's often used as wear strips, liners, and deflector plates.

Ultra-Strength Carbon Steel

The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.

Ultra-Wear-Resistant
AR500 Carbon Steel

Exceptional hardness makes AR500 carbon steel more resistant to wear and impact than other carbon steel.

Impact-Resistant A516 Carbon Steel

Even in low temperatures, A516 carbon steel resists breaking upon impact. Also known as pressure-vessel-quality (PVQ) steel, it is mostly used for boilers, storage tanks, and pressure vessels.

High-Strength 1045 Carbon Steel

Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts.
