ASTM 1045 galvanized steel coil is a high strength carbon quality steel, due to poor hardenability, generally use normalized condition, mechanical properties are higher, and the use of quenched and tempered. Moderate cold plastic deformation, annealing and normalizing machinability than good quality tone. We are ASTM 1045 galvanized steel coil in China's manufacturers and suppliers, can provide a lot of quality and cheap ASTM 1045 galvanized steel coil products. With a look at the following our ASTM 1045 galvanized steel coils mechanical properties and production process.
