Detailed introduction
Stainless steel square bar is a steel material with good corrosion resistance, heat resistance, low temperature strength and mechanical properties.
Material：304, 304L, 321, 316, 316L, etc.
Specification：Ф1.0MM or more
Stainless steel square bar specifications, material introduction：
Material: 304, 304L, 321, 316, 316L, 310S, 630, 1Cr13, 2Cr13, 3Cr13, 1Cr17Ni2, dual phase steel, antibacterial steel and other materials.
304 (18Cr-8Ni) material: As a kind of widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening phenomenon (non-magnetic, Use warm 茺-196 ° C ~ 800 ° C). Uses: household items (1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, ship parts.
Stainless steel grade:
200 stainless steel series: 201, 202 (chromium, nickel, manganese – austenitic stainless steel)
300 stainless steel series: 301, 302, 302HQ, 303, 304, 304L, 304F, 304HC, 316, 316L, 316F, 316S, 316Ti, 310, 310S, 314, 314L, 317, 317L, 321 (chromium, nickel-austen Stainless steel)
400 stainless steel series: 410, 420, 420J2, 430, 430F, 431 (ferritic and martensitic stainless steel)
Remarks: L stands for low carbon, such as 304L is lower than 304 carbon. H and S represent high temperature resistance, such as 310S is stronger than 310, and 304H is heat resistant to 304.
Stainless steel rods are round bars, hexagonal bars, square bars, flat bars, round bars, solid bars. The glossy surface is more expensive than the black leather surface, of which 303 is a unique material in the bar, belonging to the car (cut) type material, mainly used for automatic lathe cutting. Another: 304F, 303CU, 316F are also easy to cut materials. Specifications: Ф 1mm ~ Ф 280mm.
Let’s focus on the 304 stainless steel square bar。
304 stainless steel square bar
The 304 stainless steel square rod is a versatile stainless steel material with stronger rust resistance than the 200 series stainless steel. High temperature resistance is also good, the general use temperature limit is less than 650 °C. 304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, it is found in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid below the boiling temperature of ≤ 65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
