Detailed description of stainless steel brand

At present, there are hundreds of stainless steel grades in various countries. China's GB/T20878-2007 Stainless and Heat-resistant Steel Grades and Chemical Composition stipulates 143 grades, and the American ASME/ASTM stipulates nearly 200 grades. Due to the gradual revision of the standard, the stainless steel brand name is also gradually improved and unified.

There are two ways to express stainless steel grades in China. The first is according to the provisions of Article 3.11 of GB/T221-2008 Methods for Marking Steel Product Grades. The grades are expressed by chemical element symbols and Arabic numerals representing each element, and the best control value of carbon content is expressed by two or three Arabic numerals (in parts per 10000 or parts per 100000), The content of alloy elements is indicated by the chemical element symbol and the Arabic numerals (in percentage) representing the average content of the element. When the content of alloy elements is less than 1.5%, only the elements are indicated in the grade. The elements such as niobium, titanium, zirconium and nitrogen intentionally added in the steel, although the content is very low, should also be indicated in the grade.

The supply of stainless steel is tight and the demand is good. There is a long opportunity for nickel price

The output of global nickel ore may increase significantly in 2021, but Indonesia will be banned again in 2020, and due to the transition from Indonesia to a NPI producer, the possibility of recovering exports in the future is very small. However, the problem of the decline in the grade of the Philippine ore can not be solved. At present, the domestic nickel ore is likely to continue to be tight in 2021. The cost of Indonesia's NPI may be pushed up by the imposition of Indonesia's domestic trade benchmark or enforcement. Under the condition that domestic smelting is restricted by the ore side and the NPI import cost may rise again, the supply side may support the nickel price.

Effect of Nickel on Smelting Cost of Stainless Steel

Cost comparison of high nickel iron and nickel plate: compared with pure nickel, the advantages of high nickel pig iron are mainly reflected in its ability to provide steelmaking pig iron. The price of steel-making pig iron is 2530 yuan/ton, taking 12% grade of high nickel pig iron as an example, for example, the price is 1380 yuan/nickel. For high-nickel iron, the value of steelmaking pig iron presented by each nickel point is 181 yuan. That is to say, if the quotation of high nickel pig iron is within 181 yuan/nickel higher than that of nickel plate, high nickel pig iron still has cost advantage.
