Commonly Used Carbon Steel Grades (1008–1095)

Grade	Carbon Class	Carbon % Range	Typical Features	Common Applications
1008	Low Carbon	~0.08%	Excellent formability and weldability	Deep drawing, stamped parts, enclosures
1010	Low Carbon	~0.10%	Good weldability and cold forming	Tubing, automotive stampings
1018	Medium Carbon	~0.18%	Improved strength and machinability	Shafts, pins, gears
1020	Medium Carbon	~0.20%	Higher strength than 1010, decent machinability	Structural applications, axles
1040	Medium Carbon	~0.40%	Good strength, wear resistance	Gears, couplings, crankshafts
1045	Medium Carbon	~0.45%	Balanced strength and impact resistance	Bolts, rods, tool holders
1050	High Carbon	~0.50%	High strength and moderate ductility	Blades, industrial tools
1060	High Carbon	~0.60%	Higher hardness, moderate toughness	Springs, knives, agricultural tools
1075	High Carbon	~0.75%	High hardness, less formability	Hardened blades, flat springs
1095	High Carbon	~0.95%	Maximum hardness, very brittle in annealed state	Cutlery, saw blades, spring steel
