    Stainless Steel Grades and Families:Explained - Unified

    Most offer good weldability and formability in comparison to other families of steel. Some are offer improved corrosion resistance. Chloride-resistant stainless steels are especially popular in offshore use. Common duplex alloys include are 318L, LDX 2101, LDX 2304, 2507 and 4501 (Also known as 25CR superduplex) grades. Standards for reinforcementThe three grades conform to the three recommended ductility classes in BS 1992-1-1:2004 (Eurocode 2). It should be noted that below 8mm diameter, reinforcing steel to BS 4449 does not comply to BS EN 1992-1-1 with respect to ductility. This is not the only occasion where BS 4449:2005 has had to take into account the requirements of BS EN 1992-1-1.

Strength:The load a material can bear, measured by yield point and tensile strength. Yield point is the maximum point of stress at which a material will permanently change shape, and tensile strength is the point at which a bent material will break. Hardness:The level of wear resistance a material has, typically measured by a Charpy impact tGB/T 20801.1-2006:PDF in GB 5044. 3.11 Combustible medium and flammable medium A general name of grade A, grade B and fluid that operating temperature is above flash point according to definition in GB 50160. 4 Classifying of Pressure Piping Pressure piping can be divided into three grades, GC 1, GC2 and GC3 according to hazard degree and safety rating.
