904L round rod: High performance anti-corrosion performance
904L round bar is a bar form processed from 904L stainless steel, which has unique advantages in many fields. The following are your details:
904L round rod composition characteristics: It is a super austenitic stainless steel, containing a high proportion of nickel (Ni), usually in 23%-28%, nickel gives the steel excellent corrosion resistance, so that it can remain stable in a variety of harsh corrosion environments; Chromium (Cr) content is about 19%-23%, chromium can form a dense chromium oxide protective film on the steel surface, further strengthening the corrosion resistance barrier; Molybdenum (Mo) content in 4%-5%, molybdenum can effectively resist chloride ions and other aggressive medium corrosion, so the 904L round rod has excellent tolerance to seawater, chlorine-containing solutions; At the same time, it also contains copper (Cu), which helps to improve the resistance of steel to reducing acids904L round rod performance advantages:
Excellent corrosion resistance: in strong acidic, alkaline and high salinity environments are outstanding. For example, in the field of Marine engineering, in the face of continuous erosion and immersion of seawater, the 904L round rod can not rust or be corroded for a long time to ensure the structural integrity of Marine facilities; In chemical production, even contact with a variety of corrosive chemical reagents, such as sulfuric acid, hydrochloric acid dilute solution, can also maintain a good state.Good mechanical properties: Its tensile strength can generally reach 490MPa-620MPa, the yield strength is about 215MPa-310MPa, with enough strength to carry external force, while the elongation is good, to ensure that there is a certain toughness in the force deformation, to prevent sudden fracture, to meet the double requirements of material strength and toughness such as precision machining and mold manufacturing.
Excellent machining performance: easy to cut, weld, forging and other processing operations. When welding, the appropriate welding process can obtain high quality weld, and the corrosion resistance of the weld area is similar to that of the base material, and the overall performance will not be reduced due to welding. In terms of cold processing, such as cold drawing and cold rolling, it can be successfully made into round rods with different specifications and precision requirements to meet the customized needs of various industries.904L round rod application field:
Chemical industry: used to make the stirring shaft of the reactor, the heat exchange tube of the heat exchanger, the valve and pipe fittings in the pipeline system, etc., because these parts have frequent contact with various corrosive chemicals, the high corrosion resistance of the 904L round rod can ensure the long-term stable operation of the equipment and reduce the frequency of maintenance and replacement.Marine engineering: such as the ship's propulsion shaft, the key components of the seawater desalination device, the support structure of the offshore oil extraction platform, etc., relying on its seawater corrosion resistance characteristics, to ensure the safety of ship navigation and the reliable operation of Marine facilities.
Medical equipment: Some high-end medical devices, such as key components of surgical instruments, small fixed devices implanted into the human body, require materials not only non-toxic, but also have good corrosion resistance, 904L round rod just meet these stringent conditions, providing a solid guarantee for medical treatment.
