Weathering is able to remove a very small percentage of the internal stresses, and has little effect on major casting stresses. As the stress-relief can occur only by changing elastic strain to plastic strain, it is unlikely to be significant when the residual stresses are less KR F500 steel,KR grade F500,KR F500 plate - BEBON steelsell DNV AH40 steel ,DNV AH40 ship plate,DNV AH40 shipbuilding steel, steel grade DNV AH40; BBN Group Updating the Officing Buildings; Why the Weathering Steel Prices Accelerated Falling in November; How to avoid false welding when weathering steel relief welding?

As for welding any material, welder fume exposure should be minimized through the use of ventilation, fume extractors, and/or respirators, as necessary for the given conditions. Properties of Steel Understanding Material Properties

  • CharacteristicsPropertiesTypes of Steel & Their PropertiesWeldability
    Weldability is a property of steel that greatly affects how easily it can be used in construction and fabrication. A steels weldability determines how easily a material can be welded. Materials with low weldability are likely to crack due to the local stresses caused from heating at the weld joint. A materialHardenability
    If your design is going to be required for cutting or need substantial wear resistance then the hardenability property of steel should be weighed in your decision. A materials hardenability determines how easily the material can be hardened by thermal treatment. As hardenability increase, weldability decreases and viMachineability
    If you are going to have to cut or remove material for your design then the machineability property of steel should play a role in your material selection. Machineability is dependent upon a lot of factors. If a material is too hard it will reduce the tool life and dramatically increase the part costs.
