Ovako 355B The grade is inside the SAE 4340 specification but is slightly enhanced with Vanadium for improved tempering resistance. The grade has a low controlled sulphur content to ensure machinability yet with a high sulphidic cleanliness. Oxygen content is kept low for high oxidic cleanliness. The steel is of Bearing Quality cleanliness (BQ).

ASTM A829 Steel Grades. The ASTM A829 specification is the Standard Specification for Alloy Structural Steel Plates produced to chemical composition requirements and delivered in the as-rolled (green) condition. Parts produced from the as-rolled (green) plates are typically heat treated to obtained a combination of high strength and toughness.
ASTM A915 / A915M - 08(2018) Standard Specification for This specification covers carbon and low alloy steel castings having chemical analyses similar to that of the standard wrought grades. Several grades are covered, such as; SC 1020, SC 1025, SC 1030, SC 1040, SC 1045, SC 4130, SC 4140, SC 4330, SC 4340, SC 8620, SC 8625, and SC 8630.
