The specific value of the 16mn low alloy tube elongation is determined according to what
16Mn alloy tube
16Mn is called low alloy high strength structural steel
Low-alloy high-strength structural steel: carbon content is 0.1%-0.25%, adding main alloying elements manganese, silicon, vanadium, niobium and titanium; its total alloy content: C: 0.12-0.20; Mn: 1.20 -1.60; Si: 0.20-0.55;
Tensile strength: 470-660 N/mm 2 ;
Yield strength: 275-345 N/mm 2;
Elongation: 21%. The specific value should be based on the thickness or diameter of the steel. The above data corresponds to the thickness or diameter of the steel: 16-100mm
Uses: The special steel grade for bridges is “16Mnqâ€, the special steel grade for automobile girders is “16MnLâ€, and the special steel grade for pressure vessels is “16MnRâ€.
16Mn
16Mn is a material for steel. 16Mn is the name of the past, now called: Q345
16: represents the carbon content of this steel is about 0.16%.
Mn: It is proposed separately because the content of manganese in the five major elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S) is high, about 1.20 to 1.60%.
16Mn is a low-alloy steel plate series. In this series, it is the most common material, or the grade of steel plate.
According to special requirements, some special treatments can be carried out on the steel plate: heat treatment and Z-direction properties.
Stainless Steel Baking Cooling Rack
Baking rack,baking cooling mesh,Baking cooling rack,Cooling Rack, steel wire cooling rack, etc.
Baking wire mesh is made of high quality 304 stainless steel, never rusting and durable. Cooling Wire mesh does not have any coating or chemical ingredients, making food safer.
Multi-functional Grill Cooking rack: the wire mesh is mainly used for outdoor cooking, it can also be used as a cooling and baking rack. Or you can develop other uses for it.Baking Rack,Cooling Rack,Kitchen Baking Rack,Stainless Steel Cooling Rack,Oven Baking Rack
