304 Stainless Steel Strip
What is 304 Stainless Steel Strip?
The 304 stainless steel strip is the most extensively used chromium-nickel stainless steel worldwide, celebrated for its outstanding corrosion and heat resistance. It retains strong mechanical properties across a wide temperature range, from -196°C to 800°C. Known for its excellent formability, this steel can be easily shaped through processes such as stamping and bending and does not require heat treatment for hardening.
Its corrosion resistance is impressive, although regular cleaning is necessary in industrial or polluted environments to maintain its integrity. As a food-grade material, 304 stainless steel is widely used in the food industry, covering areas from processing and storage to transportation, thanks to its excellent machinability and weldability. The alloy composition includes over 18% chromium and more than 8% nickel, which are crucial for its corrosion-resistant qualities. Produced according to American ASTM standards, it also conforms to the Japanese SUS 304 specification.

Features of 304 Stainless Steel Strip
The 304 stainless steel strip is renowned for its versatility and durability across a wide range of applications. It excels in various atmospheric conditions, though it is less suitable for marine and heavily polluted industrial environments. Its aesthetic appeal remains intact with routine maintenance or natural cleansing by rain.
While highly effective in potable water environments, 304 stainless steel faces challenges in high-chloride settings. It is prone to pitting and crevice corrosion at chloride concentrations above 200 ppm. Its use in seawater is limited due to susceptibility to crevice corrosion, and exposure to chlorides above 60°C can lead to stress corrosion cracking, necessitating careful selection in corrosive environments.
This austenitic stainless steel demonstrates remarkable toughness and energy absorption in impact testing, maintaining its integrity at temperatures as low as -200°C. For grade 304 sheets, the maximum service temperatures are recommended at 870°C for intermittent use and 925°C for continuous exposure.
Characterized by excellent formability, 304 stainless steel strips are suitable for various metalworking processes, with plasma cutting preferred over oxygen cutting. Its deep drawing quality is particularly notable, making it ideal for intricate shaping.
Weldability is another strong point, compatible with most fusion welding techniques. For applications requiring enhanced corrosion resistance, particularly in welds thicker than about 6mm, opting for 304L, the low-carbon variant, is advantageous. Conversely, for high-temperature scenarios, 304H, the high-carbon variant, offers improved performance, highlighting the versatility of 304 stainless steel sheets in meeting diverse requirements.
