3J1 precision alloy is an iron-nickel-chromium austenite precipitation-strengthened high elastic alloy. After solution treatment, it has good plasticity, low hardness and is easy to process and shape. After solid solution or cold strain aging treatment, high mechanical properties and elastic properties are obtained.

3J1 alloy stripcan work below 250℃. This type of alloy can also be used at low temperatures (such as nearly -200°C).
3J1 precision alloy has the characteristics of high strength, high elastic modulus, small elastic aftereffect and hysteresis, weak magnetism, good corrosion resistance, and thermal stability, and can withstand high temperatures and large stress. Or work under corrosive media conditions.
3J1 alloy stripproduct features: high elasticity, corrosion resistance, weak or non-magnetic.
3J1 alloy stripalloy is an old brand from the 1960s and has been produced and used in China for many years. 3J1 alloy belt is mainly used to manufacture various aviation elastic-sensitive components and parts resistant to nitric acid or other corrosive media, such as membrane boxes, diaphragms, bellows, transmission rods, baffles, and other elastic structural parts.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
