When the fasteners are selected, whether the stainless steel material is magnetic or not does not indicate the quality of the fasteners. In fact, some chromium-manganese stainless steels are stainless steels that do not have magnetic properties. Chromium-manganese stainless steel in stainless steel fasteners is not a substitute for the use of 300 series stainless steels, especially in high-media corrosive working environments.
Regardless of the manufacturing, use or handling of the various links, the use of stainless steel as a material is advantageous. Of course, stainless steel is a higher cost of the material itself, and the cycle life is relatively short, but in the fastener solution However, it still belongs to a more economical one.
Analysis of magnetic problems of stainless steel fasteners
If the fasteners use stainless steel as the main material, you should also understand the magnetic problems of the stainless steel itself. Stainless steel is generally considered to be non-magnetic, but in fact, austenitic series materials may be magnetic after a certain processing process, but if it is considered that magnetic is the standard for judging the quality of stainless steel fasteners, it is not precise.
There are many types of fasteners, and the fasteners made of stainless steel are more textured in appearance, have better performance in strength, and have the advantages of corrosion resistance, easy manufacturing, and good welding. Stainless steel fasteners can be plated or heat treated for better performance and 100% recycled.
Phosphate rock powder is a natural, untreated. Phosphate rock powder is a natural, untreated phosphate. When applied to the soil, phosphate rock will become part of the soil. Once applied, the phosphate rock does not leach and it remains in the soil until it is absorbed by the plant. Phosphate contains no harmful acids, it also encourages the growth of bacteria and earthworms in the soil. Phosphate rock powder can be used as a base fertilizer once, and the fertilizer effect can be maintained for several years. At the same time, it is a kind of phosphate fertilizer. This organic fertilizer contains 28% to 32% P2O5.
