The strength of , 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.
A572 grade 42 high strength steel,Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
Difference between Q345R boiler vessel plate and ordinary Q345 plate, :Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, .
