Product information

Brand: 07Cr18Ni11Nb
Standard: GB/T4237-2015
07Cr18Ni11Nb stainless steel ‌ is a kind of high-performance stainless steel material, with excellent high temperature resistance, corrosion resistance and good processing properties, which makes it widely used in many fields. The following are the main uses of 07Cr18Ni11Nb stainless steel:
‌ high temperature environment ‌ : because of its good high temperature resistance, the highest temperature can reach 800℃, 07Cr18Ni11Nb stainless steel is widely used in high temperature environment material manufacturing, such as furnace, heating equipment, high temperature pipeline and chemical equipment ‌.
‌ petrochemical ‌ : This kind of stainless steel is widely used in the petrochemical field, including but not limited to the manufacture of pressure vessels, pipelines, valves and other equipment. Its corrosion resistance and high temperature resistance make it capable of long-term stable operation in harsh environments ‌.
‌ power industry ‌ : 07Cr18Ni11Nb stainless steel is also used in the power industry equipment manufacturing, such as steam pipes, heat exchangers pipe fittings, especially in large boiler superheater, reheater and petrochemical heat exchanger pipe fittings ‌.
‌ medical devices ‌ : due to its good corrosion resistance and processing properties, 07Cr18Ni11Nb stainless steel is also used in the manufacture of medical devices to ensure good hygiene performance and durability in the medical environment ‌.
‌ food processing ‌ : In the food processing industry, this kind of stainless steel is used to make food processing equipment and containers ‌ for its excellent corrosion resistance and hygiene properties.
‌ architectural decoration ‌ : Because of its beautiful appearance and easy to clean characteristics, 07Cr18Ni11Nb stainless steel is also widely used in architectural decoration, household goods and other fields, such as external walls, floors, interior decoration ‌.

Product parameter

Chemical composition
‌ carbon (C)‌ ranges from 0.04% to 0.10%.
The content of ‌ manganese (Mn)‌ should be no more than 2.00%.
‌ silicon (Si)‌ content should be less than or equal to 1.00%.
‌ chromium (Cr)‌ ranges from 17.0% to 19.0%.
‌ nickel (Ni)‌ ranges from 9.0% to 12.0%.
The content of ‌ phosphorus (P)‌ should be less than 0.045%.
‌ sulfur (S)‌ content should be less than 0.03%.
‌ niobium (Nb)‌ ranges from 8C to 1.10%.
Mechanical property
‌ Tensile strength (RM/MPa) ≥515‌, indicates the maximum stress that a material can withstand before it is stretched to fracture.
‌ yield strength (Rp0.2/MPa) ≥205‌ is the stress level at which a material begins to deform permanently.
‌ post-fracture elongation (A/%) ≥40‌, reflecting the percentage change of the original standard distance length after fracture, is an important index to measure the plastic deformation ability of materials.
‌ hardness (HBW) ≤201‌, is a quantitative index of the material resistance to external pressing force, the smaller the hardness value, the softer the material.
