Cumulatively, pig iron production from January to March amounted to 213.389 million tons, down by 2.9% year-on-year. Crude steel production...
Differentiating Stainless Steel from Other Materials 1. Magnetic Test A straightforward method for distinguishing annealed austenitic stainless steel from ferritic stainless steel is the magnetic test. Austenitic stainless steel is non-magnetic initially but may acquire slight magnetism after cold working under pressure. In contrast, pure chromium steel and low alloy steel exhibit...
