Brief Discussion on Sterling Stainless Steel Hardening Technology
Stainless steel hardening technology is a high-tech technical subject. Sterling enterprises are currently in the leading position in the domestic industry in the field of stainless steel hardening technology, and have applied for high-tech enterprises in Dongguan!
1. 0μm (micron), salt spray resistance test for more than 200h (316, 304).
Second, stainless steel 316, 304, etc., vacuum ion nitriding treatment (glow ion nitriding, low temperature ion nitriding)
(1) Processing temperature: 350-450 degrees; Appearance: Polished color
(2) Performance indicators: surface hardness of 1000 ~ 1400HV0.1, hardened layer depth of 8 ~ 25μm (micron), salt spray resistance test 72h or more (316, 304).
Third, stainless steel 316, 304, etc., ordinary vacuum ion nitriding treatment (glow ion nitriding hardening treatment)
(1) Processing temperature: 500-600 degrees; Appearance: Polished color
(2) Performance index: surface hardness of 1000 to 1300 HV1, depth of hardened layer of 80 to 150 μm (micrometer).
Fourth, tool steel, alloy steel, stainless iron, etc., vacuum ion nitriding treatment (glow ion nitriding). It is suitable for high-precision molds and fittings, standard parts, non-standard parts, etc., such as shafts, pins, gears, tools, etc. After processing, the workpiece has small dimensional deformation, high hardness and excellent wear resistance.
5. Vacuum ion nitrocarburizing treatment (glow ion soft nitriding) of tool steel, alloy steel and stainless steel. Compared with ion nitriding, the efficiency of ion soft nitriding is higher, the toughness of the hardened layer is better, and a thicker white bright layer is more easily obtained;It is suitable for high-precision molds and fittings, standard parts, non-standard parts, etc., such as shafts, pins, gears, tools, etc. After processing, the workpiece has small dimensional deformation, high hardness and excellent wear resistance.
Sixth, alloy steel, tool steel, stainless steel, etc., vacuum ion nitriding and oxidation composite treatment (ion nitriding blackening, vacuum ion QPQ processing)
Ion nitriding and oxidation treatment in the same furnace; the QBQ impurity pollution of the salt bath is greatly reduced compared with the vacuum furnace, the black oxide layer and the nitride layer are more uniform and tightly covered, the firmness and corrosion resistance are greatly improved, and the oil can be effectively stored. Further reduce the friction coefficient; the ion composite treatment is suitable for precision workpieces, such as automotive parts, precision molds, etc. The processed workpieces have a black color and a salt spray resistance test for more than 100 hours, which effectively reduces wear, deformation, and dimensional expansion. Controllable, technical and environmentally friendly.
7. Alloy steel, tool steel, stainless steel, etc., vacuum ion nitrocarburizing and oxidation composite treatment (ion nitrocarburizing blackening treatment, vacuum ion QPQ treatment)
Ion nitriding and oxidation treatment in the same furnace; the QBQ impurity pollution of the salt bath is greatly reduced compared with the vacuum furnace, the black oxide layer and the nitride layer are more uniform and tightly covered, the firmness and corrosion resistance are greatly improved, and the oil can be effectively stored. Further reduce the friction coefficient; ion composite treatment is more suitable for precision workpieces, such as automotive parts, precision molds, etc. The processed workpieces are black and bright, and the salt spray resistance test is more than 100h, which effectively reduces wear, deformation and size expansion. Accurate and controllable; high efficiency compared to nitriding, better toughness of hardened layer, and environmentally friendly technology.
The stainless hardening technology is quite complicated and versatile. At present, there are not many enterprises that can mature this technology in China! Since at present, only a small number of high-end hardware components have requirements for this process, most people's understanding of stainless steel hardening technology is very simple, because this heat treatment technology is not widely used in China! Therefore, the domestic production cost does not have a price advantage!
Technology changes the world, beyond the level of China's industrial manufacturing, to create a world-class anti-loose gasket manufacturing (SZJYD) brand!

DBB Plug Valve called double block-and-bleed plug valves which is high-integrity, positive shut-off valves. DBB plug valve have advantages of easy maintenanceand repair. The valve size is from 2" to 24" with matching valve pressure from class 150 to class 900. DBB plug valve normally used in oil tank in airport with double sealing to protect oil pipeline from any risks, such as fire or leakage etc.
