1. The characteristics of good metal silicon 553 in terms of content: the standard national standard metal silicon 553 requires the content of iron element to account for 0.5%, aluminum element to account for 0.5%, and calcium content to account for 0.3%. It should be as high as 98.5%, which has a good effect on steelmaking and deoxidation. When purchasing metal silicon 553, you can also ask for samples from metal silicon manufacturers for laboratory analysis. A good metal silicon 553 should meet the content requirements.
2. The characteristics of good metal silicon 553 in terms of price: Metal silicon 553 can be divided into oxygen-passing type metal silicon 553 and non-oxygen type metal silicon 553 in terms of price. The price of metal silicon 553 is higher than that of non-oxygen-type metal silicon 553. If the price of metal silicon 553 is too far from the standard price, you should pay attention to the reliability of the manufacturer's metal silicon 553 products.
