Anonymous users2024-02-06Hello, I am glad to answer for you, the hardness of 316 stainless steel is greater than the equal 90hrb, and the hardness of the general production is about 78 79hrb, and even if it is the same 316 steel grade, the heat treatment process is different, the hardness is not the same, and the hardness of the hard state is generally higher than the soft state.
Now the two most commonly used stainless steels are 304, 316 (or corresponding to the German and European standards, the main difference between 316 and 304 in terms of chemical composition is that 316 contains MO, and it is generally recognized that 316 has better corrosion resistance, and is more corrosion-resistant than 304 in a high-temperature environment.

Three: the scope of application, the field of application:
316L stainless steel is added with MO, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and can be used under harsh conditions; Excellent work hardening (non-magnetic). Excellent strength at high temperatures. 316L stainless steel is an austenitic stainless steel and cannot be strengthened by heat treatment.
It has good strength, plasticity, toughness and cold formability, as well as good low-temperature properties. Due to the addition of 2% MO on the basis of Cr18Ni8, the steel is endowed with good resistance to reducing media and pitting resistance. It has suitable corrosion resistance in various organic acids, inorganic acids, alkalis, salts and seawater.
In reducing acidic media, its corrosion resistance is much better than that of 304
Four: Overview. The corrosion resistance of stainless steel is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere. In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance.
In the range of 800-1575 degrees, it is better not to act continuously on 316 stainless steel, but when 316 stainless steel is used continuously outside of this temperature range, the stainless steel has good heat resistance. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and can be used in the above temperature ranges. Annealing is carried out in the temperature range of 1850-2050 degrees, followed by rapid annealing, followed by rapid cooling.
It is resistant to high temperatures, easy to process, and high strength. 316L stainless steel, no post-weld annealing is required.

Anonymous users2024-02-04SUS316 in the thermos cup means: a grade of stainless steel produced by the American ASTM standard.
316 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 316 is equivalent to 0Cr17Ni12Mo2 stainless steel in China, and Japan also quoted the name of the United States and called it: SUS316.
SUS316 stainless steel has good plasticity, toughness, cold denaturation and welding process performance, 316 has good high temperature strength, 316L high temperature performance is slightly worse, but the corrosion resistance is better than 316, due to the low carbon content and containing 2% 3% molybdenum, it improves the corrosion resistance to reducing salts and various inorganic acids and organic acids, alkalis and salts, and high temperature strength.
SUS316 stainless steel has good plasticity, toughness, cold denaturation and welding process performance, 316 has good high temperature strength, 316L high temperature performance is slightly worse, but the corrosion resistance is better than 316, due to the low carbon content and containing 2% 3% molybdenum, it improves the corrosion resistance to reducing salts and various inorganic acids and organic acids, alkalis and salts, and high temperature strength.
Basic features: 1. The appearance of cold-rolled products has good gloss.
2. Due to the addition of MO (2 3%), the corrosion resistance, especially the pitting corrosion resistance, is excellent.
3. Excellent high temperature strength.
4. Excellent work hardenability (weak magnetism after machining).
5. The solid solution state is non-magnetic.
6. Good welding performance. All standard welding methods can be used for welding. When welding, according to the application, 316CB, 316L or 309CB stainless steel packing rod or welding rod can be used for welding.
For optimal corrosion resistance, the welded sections of 316 stainless steel need to be annealed after welding. If 316L stainless steel is used, post-weld annealing is not required.

Anonymous users2024-02-03SUS316L is a stainless steel material.
Trademark. SUS316L is the corresponding Japanese mark, China's unified digital code is S31603, the standard grade is 022Cr17Ni12Mo2 (new standard), and the old grade is 00Cr17Ni14Mo2, which indicates that it mainly contains Cr, Ni, Mo, and the number indicates the approximate percentage.
Stainless steel material:
In layman's terms, stainless steel is a steel that is not easy to rust, in fact, some stainless steel has both stainless steel and acid resistance (corrosion resistance). The stainless steel and corrosion resistance are due to the formation of a chromium-rich oxide film (passivation film) on the surface of the sail. This rust and corrosion resistance are relative.
Tests show that steel is oxidized in weak media such as atmosphere and water and nitric acid.
When the chromium content reaches a certain percentage, the corrosion resistance of the steel changes abruptly, that is, from easy rust to not easy to rust, from non-corrosion resistant to corrosion resistance.
First, check the exterior for oil leaks.
Pay special attention to whether there is oil leakage at the oil seals at the front and rear ends of the crankshaft. Oil leakage at the front end of the crankshaft can be caused by broken or damaged oil seals at the front end of the crankshaft, aging or worn contact surfaces between the crankshaft pulley and the oil seal. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft. >>>More
