X6CrNiTi18-10 R500 Stainless Steel Plate

What is X6CrNiTi18-10 stainless steel plate?

X6CrNiTi18-10 (Material No. 1.4541) is a titanium-stabilized austenitic stainless steel plate commonly known as AISI 321 or UNS S32100. It features excellent intergranular corrosion resistance after welding, good high-temperature strength, and high-temperature oxidation resistance, making it suitable for chemical, food processing, and exhaust systems.

 

What is X6CrNiTi18-10 material equivalent to?

X6CrNiTi18-10 (material number 1.4541) is a titanium-stabilized austenitic stainless steel primarily equivalent to AISI 321 (UNS S32100). Known for excellent intergranular corrosion resistance after welding, it is commonly used in high-temperature environments (up to 900°C), such as exhaust systems, chemical processing, and heat exchangers.

 

What does "R500" mean?

R: Represents tensile strength (Rm).
500: Indicates a minimum tensile strength of 500 MPa.
Cold-worked condition: Signifies that the material is not supplied in the final solution-annealed (Soft Annealed) state, but has instead undergone cold rolling (Cold Rolled) or cold drawing (Cold Drawn) processes.

 

X6CrNiTi18-10 Stainless Steel Plate Supplier

Our X6CrNiTi18-10 R500 stainless steel plates fully comply with the EN 10088-2 standard and have undergone solution annealing treatment. This process is typically conducted at temperatures exceeding 1040°C, followed by rapid cooling, thereby ensuring the material possesses a uniform microstructure, complete dissolution of carbides, and optimal corrosion resistance.

We place particular emphasis on controlling the chemical composition,specifically the titanium (Ti) content-strictly maintaining its ratio within the range of Ti ≥ 5×C to ensure the material achieves effective stabilization. These stainless steel plates feature a yield strength (Rp0.2) of >500 MPa, a tensile strength (Rm) of ≥700 MPa, and an elongation at break (A) of ≥25%. All steel plates are accompanied by an EN 10204 3.1 material test certificate and include guaranteed reports on intergranular corrosion testing (e.g., EN ISO 3651-2), thereby ensuring that critical projects meet the highest standards regarding material traceability and regulatory compliance.

What is the difference between 1.4541/X6CrNiTi18-10 and 304 stainless steel?

The primary difference between 1.4541 (X6CrNiTi18-10 / AISI 321) and 304 (1.4301 / X5CrNi18-10) stainless steel lies in the fact that 1.4541 has undergone titanium (Ti) stabilization treatment. This treatment completely resolves the issue of susceptibility to intergranular corrosion,a common problem with 304 stainless steel following welding-while simultaneously retaining excellent corrosion resistance, high-temperature strength, and weldability. Consequently, 1.4541 is capable of sustaining long-term application in high-temperature environments ranging from 400°C to 900°C.

 

Note：

Delivery Condition: Solution Treatment + Cold Working Strengthening (SVT+R500); Third-party inspection reports (SGS/BV) are available upon request.
Lead Time: 15–20 days for standard specifications; 25–30 days for custom specifications.
Pricing: Quoted based on FOB/CIF terms, determined by specific specifications (thickness, width, length, and surface finish).

 

EN 10204 3.1 material test certificate

Regarding packaging and shipping, all stainless steel plates undergo moisture-proof treatment and are securely enclosed using methods such as wooden crates, pallets, or bubble wrap. For transportation, standard shipping containers or specialized transport vehicles are utilized to ensure the integrity and safety of the cargo throughout the transit process.

After bundling, the materials are wrapped in waterproof paper and placed on wooden pallets. The packaging is robust to prevent damage during transit and can be customized to comply with relevant regulations and client specifications. Furthermore, the exterior of each package bears clear labeling to facilitate easy identification of the product and its quality specifications.
