Non-magnetic die steel: Advantages of the new 5Cr21 non-magnetic die steel
|
|
5Cr21 non-magnetic die steel: 5Cr21 non-magnetic die steel is a new type of electroslag remelting (ESR) non-magnetic die steel developed by our factory and Shanghai Iron and Steel Research Institute. This steel has high hardness: HRC>47; Low permeability < 0.01, with the application of yunsheng strong magnetic, Dekang strong magnetic, Tianjin Photocopy, Ketian magnetic industry and other enterprises and obtain consistent praise.
GH91B: GH91B new hot rolling die material is a new special alloy material, suitable for the application of 600℃ above the field of hot processing. It has good thermal stability, wear resistance and red hardness, and excellent resistance to quenching and heating and high temperature oxidation. It has good comprehensive performance at 700℃. It is an ideal hot rolling material. Now it is used to make the rolls of non-ferrous metal copper mill, its service life can be increased 3 times than that of ordinary hot work die steel, and the rolled products have good surface quality, high dimensional accuracy, and long service life, and it has been applied to the copper processing industry for 3 years. Now the steel as a copper mill roll has been applied to the domestic famous copper processing enterprises, the effect is good, and our company has been continuous cooperation for 3 years, by the user's praise and trust.
Review on advance of new special material GH91B alloy
The roll die of copper mill is the key tool used in the production of copper mill. The service life and quality of the die greatly affect the quality, production efficiency and production cost of hot rolled products. If the traditional hot-working steel material is used to make the roll die, because of the short service life, the surface quality of the rolled products is not good, the dimensional accuracy is poor, so the die needs to be changed frequently, the production efficiency is low, the product yield is low, and the die consumption is large. GH91B alloy material developed by us has solved many problems of copper roll mould. It has been popularized and applied to the famous copper pipe processing industry, with good response from users and increasing dosage year by year, becoming an indispensable and important tool in the production of these enterprises. In the past few years, remarkable economic and social benefits have been obtained in the field of copper pipe production throughout the country and the remarkable superiority of this new material has been fully shown.
1. Improve productivity
GH91B material has a long service life. Service life is 3 times of Cr12MoV steel, can reduce a lot of hot stop mold repair time for enterprises.
2. Improve product quality
GH91B has high red hardness and good wear resistance. No deformation, no oxidation, smooth surface non-stick copper, the extruded product surface quality is good, the size of high accuracy, for the stretching process and sizing control to provide a good condition. It eliminates the phenomenon of sticking copper and scratching when using hot-working steel die.
3. Improve the yield of products
GH91B hot rolled out of the copper surface smooth, high yield.
4. Reduce mold costs
In hot rolling production, roller mold consumption is large, accounting for a high proportion of production, the use of GH91B material, is more than 3 times the service life of hot steel mold, and reduce a lot of mold machining costs. Its economic and social benefits are remarkable. It provides a guarantee for high yield, high quality and low consumption of hot rolled copper tube products, and creates a good condition for the sustainable development of non-ferrous metal processing industry.
5. Provide product specifications
We are now able to supply all kinds of forging bars of copper mill roller diameter ≤φ120mm according to the requirements of manufacturers. And various specifications of flat materials.
Non-magnetic high wear-resistant high strength stainless steel: my company to the requirements of the China petroleum logging co., LTD., the application in field work environment, requirements for downhole testing equipment corrosion resistance, high wear resistance, high strength, no magnetic energy new high strength stainless steel, fit, successful replaced the titanium tubes, is China petroleum logging co., LTD. Our company has become the designated supplier. This steel has been applied in bulk and used as a large transformer in China's west-to-East power transmission project this year, and remarkable economic benefits have been obtained.
