303 stainless steel standard 303 stainless steel how to better resist rust
With the development of our current technology, a series of scientific and technological products have been launched. They have changed our lives to some extent, making our lives more convenient. When it comes to life, it is nothing more than clothing, food, housing, and transportation. However, we are now increasingly demanding quality of life. What we bring to you today is about 303 stainless steel, a new technology product raw material. I believe everyone is not very familiar with the 303 stainless steel standard . What are the relevant provisions of the state? Today, I will focus on the topic of 303 stainless steel standards to help you further understand the relevant knowledge of 303 stainless steel.
303 stainless steel introduction
303 stainless steel, which is the most popular stainless steel on the market. Its raw material is dead to use austenitic stainless steel with free cutting, and if you want to improve its performance and improve its corrosion resistance, we can choose to add not more than 0.60% of molybdenum.
Second, after the mechanical properties of 303 stainless steel were annealed to remove its stress, its tensile strength was 515 MPa and its yield was 205 MPa. And not every type of stainless steel is known as 303 stainless steel, it is also a certain standard hardness (HRB90-100). It has a wide range of applications, including petroleum and chemical industries. In addition, it can improve cutting performance and high-temperature adhesion performance to a certain extent, so it is best suited for use in automatic lathes.
303 stainless steel density
303 stainless steel density 7.93g/cm3.
303 stainless steel composition
The 303 stainless steel composition has C: ≤ 0.15; Si: ≤ 1.00 Mn: ≤ 2.00; P: ≤ 0.20; S: ≥ 0.15; Cr: 17.00 - 19.00; Ni: 8.00 - 10.00; Mo: ≤ 0.06 and so on.
303 stainless steel applications
Petroleum, electronics, chemicals, pharmaceuticals, textile, food, machinery, construction, nuclear power, aerospace, military and other industries!
303 stainless steel prices
303 stainless steel prices are about 30 yuan a kilogram, not the same area prices are different, and the quality is also the biggest factor in determining the price, but if it is a wholesale price is a very cheap affirmation, but generally will require a certain amount of In bulk, about 4 kg or more can enjoy the wholesale price, the general quality of the price is 12 yuan a kilogram, but better in about 25 to 38.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!
303 stainless steel standard
We also said before that 303 stainless steel has a lot of applicable fields, and different fields have different standards.

Editor's summary: The above is the relevant introduction that I brought to you today about 303 stainless steel and its standard classification. Its standard classification is as many as we have seen above, so we must pay attention when choosing to purchase, but do not purchase 303 stainless steel that does not meet the requirements!

Graphite Electrodes mainly use needle coke, petroleum coke, as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, Graphite Electrode with low resistivity, graphite electrode good conductivity, graphite electrode low ash, graphite electrode uniform and compact structure, good oxidation resistance, high mechanical strength, etc.
Our graphite electrode was made of high-quality petroleum coke, needle coke, coal tar pitch and other low-ash raw materials. Processing by calcining, ingredients, mixed kneading, molding, roasting and pressure impregnation at 3000 ℃ high temperature graphite. We offers the most demanded standard graphite electrodes and nipples. Our graphite electrodes include RP, HP and UHP grades. They are widely used in electric arc furnaces (EAF) and ladle furnaces (LF) for the melting of steel, non-ferrous metals and some non-metallic minerals.
Advantage
1. High quality and strictly inspected petroleum coke, needle coke as raw material.
2. Low specific resisvitiy
3. Low conspumption rate
4. Anti-oxidation, uniform strength
5. Good resistance to thermal shock
6. Perfect match betwee body and nipple.
7. Professional , experienced reliable and safe package & transportation
