Stainless steel railing custom materials

Stainless steel railings are made of stainless steel 201, 304 and 316. They are widely used in stairs, railings, handrails, and handrails. The surface is generally brushed or gilded. Stainless steel railing and handrail custom-made main plates are generally 6-15MM thick, and most of the specifications on the market are 850*50MM or 1050*50MM in height, plus handrail joints and other accessories.

Stainless steel railings are cut by precision cutting equipment, which can be cut into various shapes, and then sheet metal processing, glass connection fasteners are mostly cast. Austenitic stainless steel The main alloying elements of austenitic stainless steel are Cr and Ni, and the matrix mainly has a face-centered cubic lattice of γ phase, which is not magnetizable. By increasing the austenite forming elements C, Ni, Mn, N and Cu, the stability of the austenitic steel can be improved. Austenitic stainless steel has good general corrosion resistance and excellent overall corrosion resistance in many media, but it is more sensitive to intergranular corrosion and stress corrosion cracking. Any heat treatment process will not harden it; but due to the increase of N content or cold forming strengthening, the mechanical properties of steel can be improved. Austenitic steel has good weldability, high low-temperature impact toughness, and high safety to prevent brittleness.

12Cr18Ni9 (1Cr18Ni9) standard 18-8 type CrNi stainless steel for general purpose. Its corrosion resistance is worse than similar 12Cr17Ni7 steel. After cold working, the tensile strength can be greatly improved, but the elongation is not as good as 12Cr17Ni7. It is used for general corrosion resistance. Fasteners mostly use machined bolts and self-tapping screws. Y12Cr18Ni9 (Y1Cr18Ni9) increases the S content on the basis of 18-8 type austenitic stainless steel to improve the cutting performance, and can add Mo and Zr elements, which is suitable for batch cutting parts, especially when using bars to process nuts.

06Cr19Ni10 (0Cr18Ni9) low carbon, CrNi stainless steel and heat-resistant steel, corrosion resistance is better than Y12Cr18Ni9 (Y1Cr18Ni9), good hot forming performance, suitable for processing fasteners by hot upsetting. For long bolts and large diameter bolts, they are beyond the scope of the cold heading process. 022Cr19Ni10 (00Cr19Ni10) has the same properties as 06Cr19Ni10 (0Cr18Ni9) except for its slightly lower strength. It is mainly used for fasteners that require welding and cannot be solid-solution treated after welding.

10Cr18Ni12 (1Cr18Ni12) is a highly corrosion resistant alloy with low work hardening rate. It is suitable for cold heading, deep stamping and spinning forming special-shaped parts. 16Cr23Ni13 (2Cr23Ni13) low carbon, high Cr and high Ni stainless steel, low carbon content, can reduce carbon precipitation during welding, is a heat-resistant stainless steel with strong corrosion resistance, corrosion-resistant fasteners used for high-temperature work. 20Cr25Ni20 (2Cr25Ni20) stainless steel with high Cr and Ni content. The corrosion resistance is similar to 16Cr23Ni13 (2Cr23Ni13), and it has better oxidation resistance at high temperatures.

06Cr17Ni12Mo2(0Cr17Ni12Mo2) Cr and Ni stainless heat-resistant steel containing Mo. Its corrosion resistance in many corrosive chemical media is better than other corrosion-resistant Cr and Ni alloys. It has good creep strength at high temperatures. For fasteners that require high-temperature strength and good corrosion resistance. 06Cr19Ni13Mo3 (0Cr19Ni13Mo3) alloy element Mo content increased, making it have better corrosion resistance. 06Cr18Ni11Ti (0Cr18Ni11Ti) Ti-containing Cr and Ni stainless steel, suitable for fasteners that are not annealed after welding or work at 430-1020°C.

06Cr18Ni11Nb (0Cr18Ni11Nb) Cr and Ni stainless steel containing tantalum and niobium, suitable for fasteners that are not annealed after welding or work at 430-1020°C.
