REGARDING STAINLESS STEEL PLATES/COIL - QUESTIONS

What are the differences between 304 and 316L?

The main difference between 304 and 316L stainless steel lies in their chemical composition. 316L contains molybdenum and has a lower carbon content, making it more corrosion-resistant and thus more suitable for high-corrosion environments such as marine and chemical industries.

What are the differences between 304L and 304?

304 has a carbon content of ≤ 0.08%, while 304L has a carbon content of ≤ 0.03%.

Can 201 replace 304?

201 Stainless steel cannot replace 304 in food contact, humid corrosion or high-reliability scenarios.

Which is more corrosion-resistant, 316 or 316L?

‌316L

What kind of environment is 321 stainless steel plate suitable for?

321 stainless steel is specially designed for use in environments with temperatures ranging from 400 to 900 degrees Celsius, where it needs to resist intergranular corrosion and oxidative media.

Why is the 310S suitable for high-temperature environments?

The 310S stainless steel strip contains a high proportion of chromium (approximately 24-26%) and nickel (approximately 19-22%). At high temperatures, it can form a dense Cr2O3 oxide film, effectively preventing further oxidation.

What are the characteristics of 2205 duplex stainless steel plate?

The 2205 yield strength is more than twice that of ordinary austenitic stainless steel, and it also possesses sufficient plasticity for forming.

In which harsh corrosive environments is 904L suitable?

Sulfuric acid solution environment / Organic acids and phosphoric acid medium / High chloride ion environment / Mixed corrosion conditions

What are the differences between 304 and 316L?

The molybdenum content of 316L is 2.0 – 3.0%, while 304 basically does not contain molybdenum.

What are the differences between stainless steel 2B, BA, and NO.1?

Stainless steel 2B, BA, and NO.1 correspond to three standard states: industrial base surface, bright annealed surface, and hot-rolled acid-etched surface.

What are the differences between cold rolling and hot rolling of stainless steel plates?

The causes of residual stress in hot-rolled steel sections and cold-rolled steel sections are different, and therefore the distribution on the cross-sections also varies significantly.

What are the specifications of the stainless steel coils?

Standard range: Thickness 0.025 – 15mm (cold rolling can reach 0.02mm, hot rolling can reach up to 15mm+),

Width: 3.5 – 2000mm (mainstream 1000/1219/1500mm), supports non-standard customization.

How is the weight of Sheets Stainless Steel calculated?

The commonly used simplified formula is: Weight (kg) = Length (m) × Width (m) × Thickness (mm) × Density (g/cm³) ÷ 1000.

How is the weight of stainless steel coils calculated?

The specific formula is: Weight (kg) = Volume (m³) × Density (kg/m³).【The 304/321/201 series is 7.93 g/cm³, the 316/316L series is 7.98, and the 400 series is 7.70 – 7.75.】

Will the Stainless Steel Floor Plate rust?

YES

Can 304 replace 316L?

NO

Can Stainless Steel Plates and Sheets Product be laser-cut?

YES

Can the stainless steel coils be cut into strips?

YES

Can stainless steel plates be bent?

YES

Can SS Plates be welded?

YES

Can the width of the stainless steel coil be customized?

YES

What kind of material certificates can the No. 1 Stainless Steel Plate provide?

Original factory quality certificate (MTC/quality guarantee certificate), third-party test report, MSDS transportation certification or metallographic/corrosion specific test report.

What are the common defects of Stainless Steel Plates and Strips?

The core defects include scratches, roll marks, pinholes, oxidation color, edge waves, delamination, pores and cracks, etc.

How to determine the quality of Stainless Plate?

The surface is smooth and the color is uniform. It has excellent flatness, the length and width meet the requirements, the thickness deviation is strictly controlled, and the diagonal deviation is in line with the requirements.

How to choose stainless steel plate products and stainless steel coils?

The sheet selection is suitable for continuous stamping / cutting strips / custom length and large quantities. The plate selection is suitable for direct cutting use, thick specifications (usually > 3mm) or scenarios requiring tolerance sensitivity.

What factors affect the price of BEST Stainless Steel Plates ?

Raw material cost drive / Market supply and demand and seasonality / Steel mill policies and futures market conditions / Process differences

Which one has a higher price, 304 or 316L?

316L 

Which has a higher price, hot-rolled coils or cold-rolled coils?

Cold-rolled coil

How is the price of stainless steel coils calculated?

Core calculation formula:
Total price of the entire roll‌ = Market benchmark ton price (yuan/ton) × Actual weighed weight (tons) + Premium adjustment + Additional processing fee


‌Ton price converted to square meter price‌ = Ton price ÷ [1000 ÷ (Thickness mm × Density g/cm³)] = Ton price × Thickness × Density ÷ 1000


‌Interconversion between sheet and plate‌: Plate unit price = Plate unit price × (Actual thickness/Theoretical thickness) + Opening and leveling fee; vice versa.

What is the minimum order quantity for JBLstainless steel plates?

Starting from 1 ton

How long is the delivery cycle for the stainless steel?

In-stock items: 1–3 days; standard custom orders: 7–15 days; complex or large-volume custom orders: 15–30 days.

Which countries can Stainless Steel Plate/Sheet be exported to?

In 2026, the main active export markets will be Vietnam, Thailand, Malaysia, Indonesia, Russia, Pakistan and some Middle Eastern countries. However, there are significant trade barriers in the United States, Japan, South Korea, Turkey, Brazil, Mexico and some member states of the European Union

How can we ensure the consistent quality of Wholesale Stainless Sheets from different batches?

The production process, raw material selection and quality control system of the stainless steel plate manufacturer.

Can stainless steel coils be directly processed into SS Sheet?

YES

How can deformation be prevented after processing of stainless steel coils?

Material pre-treatment – Process parameter optimization – Equipment and tooling guarantee – Post-treatment stability
