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
