Grade 70 chain hardness
WebThe surface hardness of the direct-quenched SAE 8620 steels can reach 37˜43 HRC. Even after tempering at temperatures higher than 400°C, the SAE 8620 steels still exhibit well-satisfied strength for Grade 80 lifting chain and fittings [5,6]. The SAE 8620 steels also exhibit excellent performances of forging, welding, and machining. WebGrade 70 Transport Chain offers greater hardness and ultimate durability. Transport chain is primarily used and tow and binder chain in agriculture, construction, industrial, trucking and forestry. All of our Grade 70 Transport Chain is 100 percent Proof Tested.

WebG80 alloy chain is rugged, versatile, high-strength, low-weight chain. Quenched and tempered before proof testing, Grade 80 chain specs & dimensions have tensile strength twice of ordinary steel chain. Peerless Grade 80 chain meets the latest guidelines of the National Association of Chain Manufacturers (NACM) and ASTM A391/A391M. WebThe most straightforward answer is that Rockwell hardness refers to how resistant a metal object such as a knife blade is to penetration and permanent deformation from another material. It’s a measuring system of non-destructive metallurgical testing that determines how hard and strong steel such as that used in knife-making truly is.
