The low melting point of tin will has a negative impact on billet
thermoplastic, which can adversely affect hot workability during
manufacturing process. But on the other hand, tin itself has excellent
corrosion resistance [11], and it was reported that a small content of
tin (about 0.05 wt.%) could improve the corrosion resistance of steel
[13], so the cost of steel would be reduced if tin was added into steel
