Grade 1Cr17Ni7
Chinese ISC S30110
The old grade corresponds to the standard GB T 4237-2015
Stainless steel, hot-rolled steel plates and strips.
hot rolled stainless steel plate,sheet and strip
Classified as austenitic stainless steel.
Performance: Corrosion resistant.
Label: Austenitic stainless steel.
Note The surface processing type of steel plate and steel strip is shown in Table 31 of the original, and the buyer should specify the surface processing type of steel plate according to the use requirements. For example: 304 1U, 304 1C, etc. 1U - hot rolled, not heat treated, no peeling; 1C - Hot rolled, heat treated, unpeeled. After negotiation between the supplier and the buyer, and indicated in the contract, the type of surface treatment other than Table 31 of the original can be provided.
The edge states of steel plates and strips are classified as: trimmed-ec; No trimming (burr) - em, the buyer can specify the edge state of the steel plate when ordering.
1Cr17Ni7 chemical element composition content (%)
1Cr17Ni7, also known as 301 stainless steel, is a corrosion-resistant stainless steel widely used in industrial fields. It has good corrosion resistance, wear resistance, welding performance and processing performance, so it is widely used in making corrosion-resistant parts, kitchen utensils, chemical equipment, etc.
1. Characteristics. 1.Corrosion resistance: 1Cr17Ni7 has excellent corrosion resistance, mainly due to its 17% chromium content. Chromium can form a dense protective film of chromium oxide with oxides, preventing the internal metal from continuing to oxidize.
2.Abrasion resistance: 1Cr17Ni7 has high hardness and good wear resistance.
3.Welding performance: 1Cr17Ni7 has excellent welding performance and can be welded by various welding methods.
4.Machining performance: 1Cr17Ni7 has good machining performance, and can be turned, drilled, milled and other processing.
2. Application. 1.Corrosion-resistant parts: Because 1Cr17Ni7 has good corrosion resistance, it is widely used in making corrosion-resistant parts, such as screws, nuts, gaskets, etc.
2.Kitchen utensils: The corrosion resistance and abrasion resistance of 1Cr17Ni7 make it an ideal material for making kitchen utensils, such as knives, pots and pans, kitchenware, etc.
3.Chemical equipment: 1Cr17Ni7 is also widely used in the chemical field, which can be used to make storage tanks, pipelines, valves, pumps and other equipment.
4.Medical equipment: Since 1Cr17Ni7 has good biocompatibility, it is also widely used in the medical field, such as making syringes, syringes, etc.
3. Parameters. 1.Chemical composition: The chemical composition of 1Cr17Ni7 is: Carbon C 015%, silicon si 10%, manganese mn 10%, phosphorus p 0035%, sulfur 0030%, chromium CR 160%-18.0%, nickel Ni 60%-8.0%。
2.Mechanical properties: The mechanical properties of 1Cr17Ni7 are as follows: tensile strength B 520MPa, yield strength S 205MPa, elongation δ 40%.
3.Heat treatment: 1Cr17Ni7 can be heat treated by solution treatment, annealing, normalizing, etc.
4.Physical properties: The physical properties of 1Cr17Ni7 are as follows: density 793g cm, melting point A1 1314-1330, magnetic 10%。
To sum up, 1Cr17Ni7 has good corrosion resistance, wear resistance, welding performance and processing performance, and is widely used in the production of corrosion-resistant parts, kitchen utensils, chemical equipment, etc. Its parameters such as chemical composition, mechanical properties, heat treatment and physical properties all meet the needs of the industrial field.
