Product Description
Stainless steel, an epitome of versatility, is meticulously categorized based on its processing methods: pressure working steel and cutting steel. Delving deeper, it unveils five distinctive structural types: austenitic, austenite-ferritic, ferritic, martensitic, and precipitation hardening. Each type carries its unique set of attributes and applications, showcasing the adaptability of stainless steel across various industries.
Stainless steel rods are the cornerstones of numerous industries and are renowned for their extensive applicability. They find their place in the crafting of hardware kitchenware, the robust shipbuilding sector, the intricate petrochemical industry, and the precise machinery and medical fields. They are indispensable in the production of food, the harnessing of electricity, the provision of energy, and the realms of construction and decoration.

Stainless Steel, renowned for its impeccable corrosion resistance and enduring stainless qualities, is defined by its composition: at least 10.5% chromium and no more than 1.2% carbon. This unique formulation endows it with remarkable durability and resilience, making it an ideal choice for demanding environments and applications.
Stainless steel rods, with their expansive application potential, are indispensable across many sectors. From hardware kitchenware to shipbuilding, petrochemicals, machinery, medicine, food production, electricity, energy, construction, and decoration, to the rigorous demands of nuclear power, aerospace, and military uses, they are integral. These rods are essential in seawater equipment and various industrial processes involving chemicals, dyes, and papermaking, as well as in the production of oxalic acid and fertilizers. They are also a mainstay in the food industry and coastal facility construction, frequently used in the manufacture of ropes, CD rods, bolts, and nuts.
Main Features
1. Weldability
Different product uses have distinct demands for welding performance. While items like tableware often bypass welding needs, a world of functionality depends on seamless joints. Consider second-class tableware, thermos cups, steel pipes, water heaters, and water dispensers; these essentials rely on the superior welding prowess of raw materials to ensure durability and longevity.
2. Corrosion resistance
Stainless steel products shine with their outstanding corrosion resistance, a pivotal trait for Class I and II tableware, kitchenware, water heaters, and dispensers. International standards often involve rigorous tests, like immersing products in a heated NACL solution. Post-boiling, the solution is drained, the product is washed, dried, and its weight loss is measured to evaluate corrosion levels. Take note: when polished, iron content from abrasive materials can induce surface rust spots during testing.
3. Polishing performance
In the modern manufacturing landscape, the gleam of stainless steel is crucial, with many products subjected to polishing. Few exceptions, such as internal components of water heaters and dispensers, may forgo this step. Superior polishing performance of raw materials is essential. Several factors influence this, ensuring that the finished product meets aesthetic and functional standards.
(1)Surface defects of raw materials. Including issues like scratches, pitting, and pickling that can mar the final finish.
(2)The attributes of raw materials. Optimal hardness is key; too low and polishing becomes challenging, while deep drawing may result in undesirable surface textures like orange peel. Conversely, materials with higher hardness deliver better BQ properties.
(3)Deep-drawn products face unique challenges. Areas with significant deformation may develop small black spots and ridging, compromising the BQ performance essential for a pristine finish.
4. Heat resistance
Heat resistance denotes the ability of stainless steel to maintain its remarkable physical and mechanical properties at elevated temperatures, ensuring reliability in demanding environments.
The Role of Carbon: Carbon is a pivotal element in austenitic stainless steels, forming and stabilizing austenite while expanding its region. Its capacity to form austenite is about 30 times greater than nickel's. As an interstitial element, carbon significantly enhances the strength of austenitic stainless steel via solid solution strengthening and bolsters stress corrosion resistance in high-concentration chloride environments, like a 42% MgCl2 boiling solution.
