The carbon content of stainless steel 304l plate is ≤0.03% (lower than the 0.08% of conventional 304). The ultra-low carbon design completely eliminates the risk of chromium carbide precipitation in the welding heat affected zone, and the intergranular corrosion rate is reduced by 70%. Its composition of 18.2% chromium + 9.1% nickel (with a third-party spectrum report), the annual corrosion rate in 5% sodium chloride solution is <0.002mm (carbon steel is 0.1mm), the salt spray test is >500 hours without red rust, and the extreme temperature tolerance range is -196℃~450°C(the actual impact toughness at -196°Cis 185J, without the risk of brittle cracking).
1.Surface treatment
8 processes are available, including 2B matte (Ra≤0.4μm, easy to clean), BA mirror (reflectivity ≥85%), NO.4 frosted (anti-scratch architectural decoration).
2.Precision cutting
Laser cutting (tolerance ±0.1mm), striping (width ±0.3mm), reducing customer scrap rate by 15%.
3.Special processing
Support welding groove prefabrication (adapt to ASME pressure vessel standards), coating protection (avoid transportation scratches).
4.Technical guarantee
Online leveling machine ensures flatness ≤1mm/m² (national standard requires ≤3mm/m²).
1.Equipment accuracy:
20-roller Sendzimir rolling mill: thickness tolerance ±0.005mm (hairline 1/20), plate surface flatness leading the industry;
Argon protection annealing furnace: temperature control ±3°C grain size reaches ASTM grade 8 (national standard grade 7 is qualified).
- Production capacity is guaranteed:
we can stably produce no less than 30,000 tons of products every year, and there are 1,000 tons of goods in the warehouse all year round. The best-selling specifications such as 2 mm, 3 mm, and 5 mm are all in stock. If there is an emergency, the order can be shipped within 72 hours after placing the order, which is much faster than the average time of 7 days in the industry; even if it is a custom order, it can be delivered in a maximum of 7 days, while peers generally take 15 days.
- Quality control is also strict:
each roll of 304L stainless steel plate must be tested by an online spectrometer to ensure that the composition fluctuation does not exceed 0.5%, and X-rays must be used for flaw detection to ensure that 100% of the defects can be found. In addition, we have a set of "three inspections" process in operation: raw materials must be inspected as soon as they enter the warehouse, random samples will be inspected during production, and comprehensive inspections must be carried out before leaving the factory. Each link has clear standards and is not ambiguous at all. Finally, the EN 10204 3.1 certificate will be attached when the goods are shipped.
Free samples are provided for non-standard customized orders. For delayed delivery exceeding 72 hours (for spot orders), 0.5% of the order amount will be compensated on a daily basis. For product quality issues, full compensation will be paid.

Frequently Asked Questions
Q: Do you offer discounts for bulk orders?
A: Yes, we have tiered pricing for bulk orders. The larger the quantity, the more competitive the price.
Q: What is the minimum order quantity (MOQ) for custom products?
A: The MOQ for custom products depends on specifications, but generally starts from 1 pieces. For special cases, we can discuss further.
Q: Can you print our company logo on the products?
A: Yes, we can print your logo via laser engraving or stamping, as long as you provide the design file.
Q: How do you pack the products to avoid damage during shipping?
A: We use seaworthy packaging: small products in cartons or wooden crates, and large ones in steel frames or pallets with waterproof film.
Q: Do you have experience exporting to our country/region?
A: We have exported to over 50 countries, including the US, EU, Southeast Asia, and the Middle East. We're familiar with local import regulations.
