304L Stainless Steel Bar

Similar to 304 stainless steel, 304L stainless steel has one key difference in its chemical composition. The maximum carbon content of 304 stainless steel is 0.08%, whereas grade 304L stainless steel has a maximum carbon of only 0.03%. This is why the “L” in 304L can be interpreted as extra-low carbon. It is usually used to produce equipment and parts that demand better corrosion resistance and formability.

Product Description

304L Stainless Steel Bar Description

304L stainless steel bar is used where welding is involved, as a variant of 304 stainless steel bar. The lower carbon content greatly lowers the precipitation of carbides in the heat-affected zone close to the weld, and such precipitation is likely to lead to intergranular corrosion of stainless steel in certain settings. Basically, their is no need to anneal weld joints prior to using the completed metal form using 304L, saving time and effort. As a matter of fact, both 304 and 304L stainless steel bars can be used for many of the same applications. The differences are often minor enough that one isn’t considered massively more useful over the other. 304L stainless steel bars are commonly used as manufacturing parts in fields such as food processing equipment, building materials, automobile parts.

FAQ

Q1: What metal materials do you supply?

Jiangsu Zhongersheng is a professional manufacturer mainly supplying carbon steel, hot-dip galvanized steel, PPGI color coated steel, 201/304/316 stainless steel sheets, coils, tubes and profiles, as well as various steel structural parts. Our products serve infrastructure, photovoltaic, machinery manufacturing, chemical and new energy industries.

Q2: Can you customize material grades, thickness and sizes?

Full customization is available. For carbon steel, galvanized steel and stainless steel, thickness, width and length can be adjusted in accordance with ASTM & EN standards. Profiles can be cut and processed as per drawings, and special steel materials can be customized via production line scheduling.

Q3: What’s the difference between galvanized steel and color coated PPGI?

Hot-dip galvanized steel features pure zinc anti-rust coating with cost-effective and wear-resistant performance, suitable for steel brackets, guardrails and load-bearing structures, and supports secondary painting. PPGI takes galvanized sheet as base material with colorful coating for anti-rust & decorative purposes, widely used for factory roof/wall panels and energy storage housings. Thick galvanized steel is recommended for rainy coastal areas, while PPGI is ideal for decorative outdoor projects.

Q4: Do you have spot inventory? What’s your MOQ?

We built a 10,000-ton standardized warehouse with abundant spot stock of carbon steel, galvanized steel and stainless steel. MOQ is 1 ton for standard sizes; small samples of dozens of kilograms are acceptable. No upper limit for bulk engineering orders, mixed container loading of multiple steel types is supported.

Q5: How long is the delivery time for spot goods & customized goods?

Spot goods can be loaded within 3-7 days; simple cutting & bending processing orders take 7-10 days; mould opening & special steel customization takes 15-30 days, subject to specific specifications confirmation.
