Stainless steel channel steel is a long strip of steel with groove section shape. Stainless steel channel steel is divided into ordinary channel steel and light channel steel.
Stainless steel production of stainless steel channel steel materials are commonly used: 201,202,301,304,321,316,316 L, special materials can be customized.
(1) Main uses of hot rolled stainless steel ordinary channel steel: ordinary channel steel is mainly used in building structure, vehicle manufacturing and other industrial structures. It is often used with I-beam.
(2) Hot rolled stainless steel light channel steel (yb164-63) hot rolled light channel steel is a kind of steel with wide legs and thin wall, which has better economic effect than ordinary hot-rolled channel steel.

200 series: Cr Mn Ni
201: it is a high manganese and low nickel stainless steel with low nickel content and poor corrosion resistance. It is widely used in all kinds of tabletops, countertops, kitchenware, outdoor decoration engineering, urban decoration industry and high-grade household products.
202: stainless steel is widely used in architectural decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places.
300 series: Cr Ni austenitic stainless steel
301: good ductility, used for molding products. It can also be hardened rapidly by machining. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.
302: the corrosion resistance is the same as that of 304. Because the carbon content is relatively high, the strength is better.
303: it is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304: general model; 18 / 8 stainless steel. Products such as: corrosion resistant containers, tableware, furniture, railings, medical equipment. The standard ingredient is 18% chromium plus 8% nickel. It is a non-magnetic stainless steel whose metallographic structure cannot be changed by heat treatment. The GB brand is 06cr19ni10.
304 L: it has the same characteristics as 304, but it is low carbon, so it is more corrosion resistant and easy to heat treatment, but its mechanical property is poor. It is suitable for products that are welded and difficult to heat treatment.
304N: with the same characteristics as 304, it is a nitrogen-containing stainless steel. Nitrogen is added to improve the strength of the steel.
309: better temperature resistance than 304, up to 980 ℃.
309S: with a large amount of chromium and nickel, it has good heat resistance and oxidation resistance. Products such as heat exchanger, boiler components and jet engine.
310: excellent high temperature oxidation resistance, with a maximum service temperature of 1200 ℃.
316: after 304, the second most widely used steel is mainly used in food industry, watch accessories, pharmaceutical industry and surgical equipment. Molybdenum is added to obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18 / 10 stainless steel generally meets this application grade.
316 L: low carbon, so it is more corrosion-resistant and easy to heat treatment. Products such as chemical processing equipment, nuclear power generator and refrigerant storage tank.
321: in addition to reducing the risk of weld corrosion due to the addition of titanium, other properties are similar to 304.
347: add stabilizing element niobium, which is suitable for welding aviation appliance parts and chemical equipment.
400 series: Ferritic and martensitic stainless steel, manganese free, can replace 304 stainless steel to a certain extent
408: good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409: the cheapest model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).
410: martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.
416: sulfur was added to improve the processability of the material.
420: "cutting tool grade" martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. It is also used for surgical tools, which can be made very bright.
430: ferritic stainless steel, for decoration, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
440: high strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach 58hrc. It is one of the hardest stainless steels. The most common application example is "razor blade". There are three common models: 440A, 440b, 440C, and 440f (easy to process).
500 Series: heat resistant chromium alloy steel.
600 Series: Martensitic precipitation hardening stainless steel.
Element action
Carbon ( C ): 1. Improve the deformation resistance and tensile strength of the blade; 2. Increase hardness and wear resistance.
Chromium (CR): 1. Improve hardness, tensile strength and toughness; 2. Wear and corrosion resistance.
Cobalt (CO): 1. Increase hardness and strength so that it can withstand high temperature quenching; 2. It is used to strengthen some individual properties of other elements in more complex alloys.
Copper (Cu): 1. Enhance corrosion resistance; 2. Enhance wear resistance.
Manganese (MN): 1. Increase hardenability, wear resistance and tensile strength; 2. Removing oxygen from molten metal by separation oxidation and separation vaporization; 3. When added in large quantities, it improves the hardness, but improves the brittleness.
Molybdenum (MO): 1.Enhance strength, hardness, hardenability and toughness; 2. Improve machinability and corrosion resistance.
Nickel (Ni): 1. Enhance strength, hardness and corrosion resistance.
Phosphorus (P): 1. Enhanced strength, machinability and hardness. 2. It is easy to crack when the concentration is too high
Silicon (SI): 1. Improve ductility; 2. Increase tensile strength; 3. Remove oxygen from molten metal by separate oxidation and separate vaporization.
Sulfur (s): 1. Use in small quantities to improve machinability.
Tungsten (W): 1. Increase strength, hardness and toughness.
Vanadium (V): 1. Increase strength, hardness and seismic resistance.2.Prevent the generation of particles.
Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the most cost-effective materials selected by architects. Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.
