\"51CrV4<\/p>\n

51CrV4 \/ 1.8159 Spring Steel<\/b><\/strong>\u00a0<\/b><\/strong>is chromium vanadium type spring steel. It\u2019s a similar alloy steel to 5150 steel with small, but effective, vanadium addition, to import greater hardness. \u00a051CrV4 \/ 1.8159 Spring Steel\u00a0has low distortion properties and is easily heat treated. 51CrV4 \/ 1.8159 Spring Steel grade is suitable for oil hardening and tempering.<\/p>\n

51CrV4 \/ 1.8159 Spring Steel is usually supplied in the as rolled condition. When used in the oil hardened and tempered condition \u00a051CrV4 \/ 1.8159 Spring Steel\u00a0combines spring characteristics with excellent resistance to both abrasion and shock. Hardened \u00a051CrV4 \/ 1.8159 Spring Steel\u00a0offers excellent toughness and shock resistance which make it a suitable alloy spring steel for parts exposed to stress, vibration and shock.<\/p>\n

Forging of Material 51CrV4 \/ 1.8159 Spring Steel<\/strong><\/h2>\n

51CrV4 \/ 1.8159 Spring Steel\u00a0could be forged between 2150 and 1600\u00baF (1175 and 870\u00baC.) The alloy should be slow cooled after forging or transferred to a furnace around the \u2018finishing\u2019 temperature. Do not forge below 840\u00b0C.<\/p>\n
