Product Description

Product Description

Product Introduction

Stainless steel rod is a long stainless steel profile processed via smelting, rolling, cold drawing and polishing, with cross sections including round, square and hexagonal. As an essential material for industrial and civilian use, it features a dense chromium oxide passivation film on the surface, delivering superior corrosion resistance, mechanical strength and workability. Tailored by different grades and specifications, it suits harsh working conditions and is widely applied in machinery, construction, chemical, medical and food industries with good durability.
 
According to production processes, it can be classified into hot-rolled, cold drawn and polished types; based on surface conditions, there are black skin, acid washed and bright bars. Material categories include austenite, ferrite, martensite and precipitation hardening stainless steel. It supports customized dimensions, tolerances and surface treatments to meet diverse demands from daily decoration to high-precision manufacturing and non-standard applications.

Product Features

Excellent corrosion resistance: Protected by a dense chromium oxide passivation layer, it resists corrosion from moisture, acid, alkali and salt. Special grades such as 316 and 444 provide superior resistance to seawater, pitting and stress corrosion, enabling long-term service in harsh environments with low maintenance.
 
Stable mechanical performance: Stainless steel rods deliver high strength, hardness and toughness. Austenitic grades offer good formability; martensitic types provide high hardness and wear resistance; precipitation hardened steel achieves ultra-high strength, meeting diverse load requirements.
 
Superior processability: Suitable for turning, welding, bending and other machining operations. Hot rolled, cold drawn and free-cutting grades cater to rough processing, precision machining and mass production with high efficiency.
 
Wide temperature adaptability: High-temperature resistant grades maintain stability at extreme heat, while austenitic steel retains toughness at low temperatures, suitable for high-temperature equipment and cryogenic applications.
 
Attractive appearance and easy maintenance: Polished surfaces provide a sleek finish for decorative and high-end applications. The material is hygienic, easy to clean and durable for long service life.
 
Customizable specifications: Comprehensive size range with adjustable dimensions, lengths and tolerances. High precision cold drawn rods and custom designs meet specialized and non-standard application needs.

Product advantage

1.Outstanding cost-effectiveness: Compared to other metal profiles, stainless steel bars have corrosion resistance, wear resistance, and long service life, without frequent replacement and maintenance. Long term use can significantly reduce overall costs; The gradient of different materials is complete, and the appropriate grade can be selected according to the scene to avoid cost waste caused by excessive material selection. For example, 304 grade is selected for ordinary atmospheric environments and 316 grade is selected for seawater environments, achieving the optimal match between cost and performance.

2.Reliable and guaranteed quality: The production process strictly follows national standards such as GB/T 4226, adopts AOD/VOD refining technology, and the raw material purity is high with low impurity content; After multiple quality inspection processes (size inspection, surface inspection, chemical composition analysis, mechanical performance testing), the product ensures accurate size, stable performance, and no defects such as cracks, folds, scars, etc. It can pass ISO9001 quality system certification, and some products can meet export standards.

3.Highly adaptable: materials, specifications, and surface treatment methods can be customized, suitable for various scenarios ranging from ordinary civilian decoration to high-end precision manufacturing, from room temperature environments to high/low temperature/corrosive environments; Flexible processing performance, capable of implementing various processes such as cold processing, hot processing, welding, etc. It can be processed into various components according to customer drawing requirements without the need for additional adaptation and adjustment.
