There are stainless components for locking products, the cylindrical components and various other locking parts.
Besides from CNC machining and lathing, but have we produced a lot of parts from sheet stainless. For examples, we worked out a lot of covers, boxes, structures and housings for electronic products.
Sibai did also a lot of stainess material from lost wax casting (Investment casting). Sibai has rich experience on casting stainless.
The stainless 1.4301 can be also explained as EN X5CrNi18-10. It is equivalent to AISI/ASTM/UNS 304. This material is widely used due to its excellent intergranular corrosion resistance, good cold deformability, good deep drawability and weldability. What’s more, EN X5CrNi18-10 is non-magnetic in the annealed state, but it may become slightly magnetic due to the addition of martensite or ferrite during cold working or welding.
DIN EN 1.4305 stainless steel (X8CrNiS18-9 material), equivalent to 303, has a higher sulfur content and contains 1.0% copper. It is a corrosion resisting material with sulfur added to improve cutting performance, but its corrosion resistance is limited in acid and chloride media. And its toughness is also decreased slightly. X8CrNiS18-9 steel is particularly suitable for machining. And the surface after machining shows more bright.
DIN EN 1.4401 material (X5CrNiMo17-12-2) is a molybdenum-containing austenitic stainless steel. Due to the chemical composition of molybdenum, its corrosion resistance is higher than 1.4301 (X5CrNi18-10), especially in environments containing chloride and non-oxidizing acids. 1.4404 (X2CrNiMo17-12-2) is an ultra-low carbon version of 1.4401 stainless steel, which has better corrosion resistance in welded structures.
EN 1.4404 (X2CrNiMo17-12-2), equivalent to 316L, is a low-carbon version of 1.4401 (X5CrNiMo17-12-2), the maximum carbon content is only 0.03%, while 1.4401 is 0.07% maximum, so the weldability and corrosion resistance of 1.4404 stainless steel is better than 1.4401. EN 1.4404 also contains molybdenum (Mo), which improves the heat resistance of steel and resists pitting and crevice corrosion in environments containing chlorides or other halides.
EN 1.4571 (X6CrNiMoTi17-12-2), equivalent to 316Ti, is a titanium version of 316 Stainless Steel. EN 1.4571 contains a minor percentage of titanium (around 0.5%) in its alloy composition. The titanium atoms strengthen the structure of type 316 at temperatures above 800℃. This helps to avoid carbide precipitation at the grain boundaries and protect the material from corrosion. It is appropriate for extensive application in the high-temperature environment.Most of the mechanical properties of 316 type remain same in 1.4571 grade. En 1.4571 grade is a non-magnetic material.It can be used in the chemical processing industry. It can be welded.
Sibai adopts stainless material generally from DIN standard, 1.4301, 1.4305, 1.4401, 1.4404, 1.4571, and also from ASTM standard, SS 304, SS 303,SS 316, SS 316L, SS 316Ti.
They are almost the same kinds of stainess. Among the DIN standards and the ASTM materials and GB standard materials, there’s very little different in microelement compositions. So for most of the industries, the 3 standards of material can be equivalent and substitudes. They are conventional austenitic stainless steel with good resistance to atmospheric, organic and inorganic chemicals.
1. Sibai selects large stainless steel raw material manufacturers to ensure that the raw materials meet the standards and meet the production requirements of the orders.
2. Sibai chooses appropriate milling tools for mill stainless steel.
3. Sibai adopts suitable CNC machines to ensure efficient production capacity.
