X2CrNiMoCuN 25-6-3 The stainless steel rod
1.Product Description
Grade 630 stainless steels are martensitic stainless steels that are precipitation hardened to achieve excellent mechanical properties. These steel achieve high strength and hardness following heat treatment. The heat and corrosion resistance of grade 630 are similar to that of grade 304 steels. This grades is also commonly referred to as grade 17-4PH.
One of the key benefits of this grade is that it is available in solution treated conditions, at which they can be easily machined and age-hardened to attain high strength. The age treatment of grade 630 is carried out at low temperatures, to avoid significant distortion. Therefore, this grade is used for applications such as the manufacture of long shafts that do not require re-straightening after heat treatment.
Section A
Our company is one of the biggest suppliers of stainless steel bar in North China. For the 304 stainless steel bar, it has excellent resistance to acid, heat, corrosion resistance, making it an ideal basis for commercial application of material.
For the 304 stainless steel bar, the former belongs to nickel, with a capacity of more than 85%, which is chromium, the use of smaller amount.

Section D
Application:
Stainless Steel bar applies to construction field, ships building industry, petroleum and chemical industries, war and electricity industries, food processing and medical industry, boiler heat exchanger, machinery and hardware fields.
Heat Treatment
Stainless steel grade 420J2 has to be heated uniformly to 730-790°C (1346-1454°F) and held until temperature is uniform throughout the section.
Hardening
Stainless steel grade 420J2 can be hardened by heating 950-1020°C (1742-1868°F) and held until temperature is uniform throughout the section. This should be followed by quenching in oil or air cooling. Tempering should be done when it is slightly warm.
Applications
Stainless steel grade 420J2 is used in the following application areas:
Surgical instruments
Daggers and swords
Budget knives and diving knives
Haircutting scissors and domestic scissor
304LN en1.4311 stainless steel rods
Stainless steel round steel according to the production process can be divided into hot rolling, forging and cold drawn three kinds. The specifications of the hot rolled stainless steel round bar is 5.5 to 250 mm.
Among them: 5.5-25 mm small stainless steel round bar mostly to straight into a bundle of supplies, commonly used for reinforcement, bolt, and various mechanical parts; Greater than 25 mm stainless steel
round steel, mainly used in the manufacture of mechanical parts and seamless steel tube billet.
