The main function of boron in 1.8928 material composition and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 1.8928 material composition. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: 1.8928 material composition Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: 1.8928 material composition Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
In March, the daily output of key iron and steel enterprises fell on a month on month basis, while the overall inventory of 1.8928 material composition and so on steel materials was lower but still at a high level. In terms of production, in March, according to the key statistics, the cumulative average daily output of pig iron, crude steel and steel for iron and steel enterprises was 1.824 million tons, 1.695 million tons and 1.766 million tons respectively, down 2.1%, 3.1% and 1.7% on a month on month basis.
