  • Detail

303 stainless steel is a free cutting stainless wear-resistant acid steel with austenite type containing sulfur and selenium respectively, which is used in occasions requiring free cutting and high surface finish. 303 stainless steel is austenite type free cutting stainless wear-resistant acid steel. In order to improve the performance of this steel, no more than 0.60% molybdenum can be added to the steel, which can resist ablation. 303 is a free cutting stainless steel containing sulfur and selenium respectively, which is used in occasions where free cutting and high surface finish are mainly required. 303 stainless steel improves cutting performance and high temperature resistance. Most suitable for automatic lathes, bolts and nuts

with the development of science and technology, a series of scientific and technological products have been launched. They have changed our life to a certain extent, making our life more and more convenient. Speaking of life, in fact, it's just food, clothing, housing and transportation, but now we have higher and higher requirements for the quality of life. Today, we bring you about the raw materials of new scientific and technological products &mdash& mdash; 303 stainless steel. I believe you don't know much about the 303 stainless steel standard. What relevant provisions has the state made for this? Today, I will focus on the topic of 303 stainless steel standard to help you further understand the relevant knowledge of 303 stainless steel

303 stainless steel introduction

303 stainless steel is the most popular stainless steel in our market. Its raw material is austenitic free cutting stainless wear-resistant acid steel. If we want to improve its performance and corrosion resistance, we can choose to add no more than 0.60% molybdenum

secondly, 303 stainless steel has mechanical properties. After annealing to remove its stress, its tensile strength is 515mpa and yield is 205mpa. And not every kind of stainless steel is called 303 stainless steel. It also has a certain standard hardness (hrb90-100). It has a wide range of applications, including petroleum, chemical industry and so on. In addition, it can improve the cutting performance and high temperature resistance to a certain extent, so it is most suitable for automatic lathes

303 stainless steel density

303 stainless steel density 7.93g/cm3

303 stainless steel composition

303 stainless steel composition has C: ≤ 0.15; Si :≤ 1.00Mn :≤ 2.00; P :≤ 0.20; S :≥ 0.15; Cr :17.00-19.00; Ni :8.00-10.00; Mo :≤ 0.06, etc

303 stainless steel application fields

petroleum, electronics, chemical industry, medicine, light textile, food, machinery, construction, nuclear power, aerospace, military industry and other industries

303 stainless steel price

303 stainless steel price is about 30 yuan a kilogram, the price is different in different regions, and the quality is also the biggest factor determining the price. However, if it is wholesale, the price is very cheap, but generally, it will require a certain starting batch. It is probably more than 4 kilograms to enjoy the wholesale price, and the general price of quality is 12 yuan a kilogram, But the better ones are around 25 to 38

note: this price is for reference only! Due to different regions, of course, the price will also vary. For more relevant price details, please refer to the local dealer

303 stainless steel standard

as we said before, 303 stainless steel is applicable to many fields, and the standards for different fields are also different

classification

① national standard GB ② industry standard Yb ③ local standard ④ enterprise standard q/cb

classification

① product standard ② packaging standard ③ method standard ④ basic standard

standard level

y level: international advanced level I level: international general level H level: domestic advanced level

National Standard

GB1220-84 stainless steel bar (level I) gb4241-84 stainless welded disc Park (level H) gb4356-84 stainless welded disc Park (level I) gb1270-80 stainless steel pipe (level I) gb12771-91 stainless steel welded pipe (level y) gb3280-84 stainless steel cold plate (level I) gb4237-84 stainless steel hot plate (level I) GB4239-91 stainless steel cold strip (level I)

editor's summary: the above is what I bring to you today about 303 stainless steel and its standard classification. As we have seen above, there are many standard classifications of it, so you should pay attention when choosing to buy. Don't buy 303 stainless steel that doesn't meet the requirements
