904L Stainless Steel Wire With High Qulity

Jaway steel company as a set of stainless steel manufacturing, sales and technical services as one of the world’s comprehensive steel service enterprises, long-term supply of 904L stainless steel wire.

904L stainless steel wire main components: 20Cr-24Ni-4.3Mo-1.5Cu.


904L stainless steel wire is a low carbon high nickel, molybdenum austenitic stainless acid steel, has a good activation – passivation transition ability, excellent corrosion resistance, non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid Good corrosion resistance, in the neutral chloride ion medium has a good pitting resistance, but also has good resistance to crevice corrosion and stress corrosion resistance. Applicable to various concentrations below 70 ℃ sulfuric acid, at any pressure under any pressure, any temperature of acetic acid and acetic acid and acetic acid in the mixed acid corrosion resistance is also very good.

Welding performance:

As with ordinary stainless steel, 904L can be welded using a variety of welding methods. The most commonly used welding methods for manual arc welding or inert gas shielded welding, electrode or wire metal based on the composition of the base material and higher purity, molybdenum content requirements than the base metal.

Before welding, there is no need for preheating, but in cold outdoor operations, in order to avoid condensation of water vapor, joint parts or adjacent areas can be used for uniform heating. Note that the local temperature should not exceed 100 ℃, so as not to cause carbon accumulation, causing intergranular corrosion. Welding should use a small line of energy, continuous and fast welding rate. After welding generally do not need heat treatment, for heat treatment, to be heated to 1100 ~ 1150 ℃ after the rapid cooling.


904L stainless steel wire rod machine processing performance:
904L machining features similar to other austenitic stainless steel, the process of sticky knife and the trend of hardening. The use of positive rake carbide cutting tools to vulcanization and chlorinated oil as a cutting coolant, equipment and technology should be to reduce the work hardening as the premise. The cutting speed and the amount of infeed should be avoided during cutting.
