SS 316/ 316L Plates

SS 316/ 316L Plates

Overview of SS 316 / SS 316L Plates

SS 316 and SS 316L plates belong to the austenitic family of stainless steels and are widely recognized for their performance across a variety of industrial applications. These grades offer excellent durability and are suitable for use in extreme environments. While there are slight differences in their chemical composition and characteristics, both grades deliver equivalent strength and performance in demanding conditions.

SS 316 Grade Characteristics

The SS 316 grade contains a high amount of nickel, which enhances its corrosion resistance and strength when compared to many other stainless steel grades. It is popular in the industry due to its low maintenance cost, high availability, and excellent long-term durability.

SS 316L Grade Properties

The SS 316L variant is a low-carbon modification of standard 316, offering superior resistance to acidic environments, pitting, general corrosion, and stress corrosion cracking. The addition of chromium and molybdenum improves its strength and performance under high temperature and pressure conditions. Both grades provide excellent ductility, toughness, and malleability, making them suitable for critical applications across multiple industries.

Manufacturing Process and Quality Testing

During production, Renam Alloys Inc. uses premium-grade raw materials that are sourced from reputable suppliers. These materials undergo thorough quality checks before entering the manufacturing process. To maintain superior standards, the company employs modern tools, advanced equipment, and innovative technology throughout the fabrication of SS 316/316L plates.

Each stage of production is closely monitored by experienced professionals who ensure that every plate meets the specified quality benchmarks. The following quality tests are conducted to verify the reliability and performance of the plates: Mechanical tests, positive material identification (PMI), intergranular corrosion testing, pitting resistance testing, flaring tests, flattening tests, ultrasonic testing, and chemical analysis.

Packaging and Documentation Provided

To prevent any form of damage during transit, SS 316/316L plates are first wrapped in protective poly bags and then securely packed in wooden crates, pallets, or cases that are fumigation-free and safe from external impurities. This ensures that the product arrives in perfect condition at its final destination.

The company also provides a comprehensive set of documents to validate the quality and traceability of the plates. These include: Fumigation certificates, welding procedure specifications (WPS), quality assurance plans (QAP), heat treatment charts, packaging lists (detailing net and gross weight), and commercial invoices.
