The specified nominal stress at breaking force of this grade is 1000 MPa. Grade V(100) components can be produced by using materials that are suitable for a 200°C or 380°C max imum operating temperatures. Each material has specific minimum alloying element requirements. V200 refers to grade V(100) components that have a maximum operating temperature of 200°C,V400 refers to grade V(100) components that have a maximum operating temperature of 380°C.
(a) For Grade V(100) welded master links, the steel shall contain nickel and at least one of the other elements in the minimum percentage as per Table 2.2.1 .4(B).
(b) For Grade V( 100) components including forged master links, the steel shall contain at least two of the three alloying elements as per Table 2.2.1.4(C).AS 3776 pdf free download.
