Gateway C-1020

C-1020 HOT ROLLED PLATE

Gateway C-1020 Hot Rolled plate is produced using a special Calcium treatment and controlled Sulfur process. It is pre-stress relieved and can be heat-treated and welded easily. Gateway C-1020 machines 40% better than other steels with comparable carbon content. Typical applications include:

SUB PLATES
MECHANICAL RUBBER MOLDS
BACK UP PLATES
TEM PLATES
GEARS, CAMS, JIGS
FIXTURES

PHYSICAL PROPERTIES

Gateway C-1020 is typically used in the AS-ROLLED condition but may be Annealed, Normalized or Carburized.

	Size sq in	Tensile Strength psi	Yield Point psi	Elongation % 2 in.	Reduction of area, %	Hardness B
AS ROLLED:	1	68,000	55,750	32.0	66.5	137
ANNEALED: (Heated to 1600F, furnace-cooled 30F per hour to 1290*F, cooled in air)
	1	57,250	42,750	36.5	66.0	111
NORMALIZED: (Heated to 1700*F, cooled in air)
	1	64,000	50,250	35.8	67.9	131
CARBURIZED: (At 1675F for 8 hours, pot-cooled, reheated to 1425F, water-quenched, tempered at 350F)
	1	87,000	54,000	23.0	64.2	179

IT SHOULD BE NOTED THAT NON-ALLOY STEEL GRADES DEVELOP A "CASE-CORE" RELATIONSHIP. THAT IS, THE SURFACE WILL ATTAIN A HIGHER HARDNESS THAN THE CENTER AS A RESULT OF ANY HEAT TREATMENT.
