The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. Q295NH weathering steel GB/T 4171 plate, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.
The related factors of Q295NH weathering steel GB/T 4171 plate steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different Q295NH weathering steel GB/T 4171 plate steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
