* The yield strength of SS400 steel plate tends to decrease as the steel thickness increases.
JIS G3101 SS400 steel plate is easy to weld, cut, bend, and punch, and is low in cost, making it highly versatile in application.
1. Construction field: Steel structures for factory buildings, beams/columns in civil construction, and steel structure frameworks.
2. Mechanical manufacturing: Base plates, brackets, protective covers, and other non-critical load-bearing components for general machinery.
3. Infrastructure: Small bridge components, street light poles, traffic sign poles, and water pipelines (low-pressure).
4. Other fields: Container bodies, simple shelving, welded steel sections, etc.

* Since the requirements for chemical composition, mechanical properties, and corrosion resistance mechanisms vary slightly across different standards, "equivalence" typically refers to similarities in intended use and performance rather than exact identity.
A:
We can provide official MTC factory test reports, ISO 9001 quality management system certification, and authoritative third-party inspection reports from SGS, BV, and TÜV. All documents are internationally recognized and can be used to support bidding for projects in cold regions worldwide, engineering acceptance inspections, and customs clearance for cross-border trade.
A:
High-strength low-alloy steel plates offer excellent weldability. As their carbon content is typically low (below 0.2%), they present a lower risk of cracking during welding compared to standard high-strength steel plates and generally do not require complex preheating treatments.
A:
The key advantage of high-strength low-alloy steels is weight reduction. As they offer greater strength, thinner sheets can be used to withstand the same loads, thereby reducing the overall weight of the structure; in the automotive sector, this leads to improved fuel efficiency.
A:
High-strength low-alloy steel (HSLA) is a type of steel in which small amounts of alloying elements (such as niobium, vanadium, titanium or copper) are added to enhance its mechanical properties. Compared to traditional carbon steel, it offers higher yield strength and better corrosion resistance whilst maintaining good weldability and formability.
