What Is Hot 904L Stainless Steel Plate?
Hot rolled 904L stainless steel plate is a specialized austenitic alloy designed for extreme corrosive environments. Known for its exceptional resistance to sulfuric acid and other aggressive chemicals, this material offers superior performance compared to standard 304 or 316 grades. The "hot" designation refers to the manufacturing process where the steel is rolled at high temperatures, allowing for thicker gauges and structural integrity in heavy-duty applications.
Shaanxi Jiade Group Co., Ltd. supplies premium hot 904L stainless steel plates that meet rigorous international standards. With over 15 years of experience in steel manufacturing and export, we ensure consistent chemical composition and mechanical properties across all batches. Our plates are ideal for buyers who require reliable materials for demanding industrial projects.
Key Characteristics of 904L Alloy
- Exceptional Corrosion Resistance: Outstanding performance in sulfuric acid environments up to 20% concentration at room temperature.

Frequently Asked Questions About 904L Stainless Steel
Get answers to common questions about hot 904L stainless steel plates from procurement experts. Our comprehensive FAQ covers material specifications, ordering processes, quality assurance, and technical support for your 904L steel purchases.
What is the difference between hot rolled and cold rolled 904L stainless steel plate?
Hot rolled 904L plates are processed at elevated temperatures (above 1,700°F), resulting in thicker gauges suitable for structural applications. They offer good formability and are more cost-effective for heavy-duty uses. Cold rolled plates achieve tighter tolerances and smoother surfaces but are limited to thinner gauges. For most industrial applications requiring corrosion resistance, hot rolled 904L provides the best balance of performance and value.
What thickness options are available for hot 904L stainless steel plates?
Hot rolled 904L stainless steel plates are typically available in thicknesses ranging from 3mm to 125mm. Standard widths include 1,220mm (4 feet), 1,500mm (5 feet), and 2,000mm (6.5 feet). We can accommodate custom dimensions based on your project requirements, optimizing material utilization and reducing fabrication waste.
Does Shaanxi Jiade Group provide Mill Test Certificates for 904L plates?
Yes, we provide comprehensive Mill Test Certificates (MTC) with every shipment of hot 904L stainless steel plates. These certificates include detailed chemical composition analysis, mechanical property test results, and heat treatment records. All documentation complies with international standards and can be verified by third-party inspection agencies if required.
What are the minimum order quantities for 904L stainless steel plates?
We offer flexible minimum order quantities to accommodate different project sizes. While we prefer larger orders to optimize production efficiency, we can accept smaller quantities for prototype development or urgent replacement needs. Contact our sales team to discuss your specific requirements and receive a customized quote.
How does 904L compare to 316L in terms of corrosion resistance?
904L offers significantly superior corrosion resistance compared to 316L, particularly in sulfuric acid environments. The higher nickel (23-25% vs 10-14%) and molybdenum (4-5% vs 2-3%) content provides enhanced protection against pitting, crevice corrosion, and stress corrosion cracking. While 904L costs more initially, its longer service life often results in lower total cost of ownership for aggressive chemical applications.
Can you cut 904L plates to custom dimensions?
Yes, we provide precision cutting services including plasma cutting, waterjet cutting, and saw cutting to meet your exact dimensional requirements. Our CNC cutting equipment ensures accurate tolerances and clean edges, reducing secondary fabrication work. Custom cutting services are available for both hot rolled and cold rolled 904L plates.
