Gangsteel produce ASTM A240 304 Stainless steel plates, S30400, A240 Type 304 Stainless steel cutting parts by water cutting, laser cutting and cnc cutting. ASTM a240 (chromium and chromium nickel stainless steel plate, sheet, and strip for pressure essels and general applications. a240 304 stainless steel is a common material in stainless steel with a density of 7.93g/cm3, which is also called 18 / 8 stainless steel in the industry. High temperature resistant 800 ��, with good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
06cr19ni10 and SUS304 are the common marking methods on the market, among which 06cr19ni10 generally refers to national standard production, 304 generally refers to ASTM standard production, and SUS 304 refers to Japanese standard production.
304 is a kind of universal stainless steel, which is widely used to make equipment and parts with good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. The stainless steel is produced according to ASTM 304.

The welds were produced utilizing four forms of filler supplies; the nickel-based mostly similar to Inconel eighty two, Inconel A, Inconel 617 and 310 austenitic stainless steels. This paper describes the choice of welding consumables for the joint. The comparative analysis was primarily based on scorching-cracking tests and estimation of mechanical properties. According to Varestraint exams, Inconel A showed the least susceptibility to hot cracking. Moreover, Inconel A weldment had the highest strength and complete elongation. On the other hand, the weld metals failed by ductile fracture besides Inconel 617, which exhibited blended fracture mode. At last, it was concluded that Inconel A filler materials provided the best compromise for the joint between Inconel 657 and 310 chrome steel.
Although three welds showed proper tensile energy values; the weld 316L introduced the best mechanical properties from the cost saving point of view. This group accommodates 12% to 16% chromium and 0.08% to 2.00% carbon. The excessive carbon content makes the martensitic grades respond nicely to warmth treatment to offer high mechanical power and hardness. However, the carbon is detrimental when welding and these grades are difficult to weld. The ductility of those grades is proscribed and they are not cold labored. In the heat handled condition, this group of stainless steels present a helpful combination of corrosion resistance and mechanical properties that qualify them for a variety of application.
Four different industrial filler metals had been selected for the becoming a member of of AISI 304 austenitic to AISI 409 ferritic chrome steel. These fillers have been austenitic and duplex stainless steels and a nickel-based mostly alloy. The microhardness and longitudinal tensile checks had been performed for evaluation of the mechanical properties. The microstructural analysis indicated that the dissimilar welding led to the formation of different ferrite-austenite solidification patterns in weld metals; additionally, no proof of carbide/nitride phases was detected.
The welding was carried out by the handbook gas tungsten arc welding course of using ER310, ERNiCr-3, and ER446 filler metals. The weld metallic microstructure of the ER310 and ERNiCr-3 filler metals was absolutely austenitic.

Specific requirements are specified by product standards. It is considered that 304 stainless steel can be considered as long as Ni content is more than 8% and Cr content is more than 18%. This is why the industry will call this kind of stainless steel 18 / 8 stainless steel. In fact, the relevant product standards have very clear provisions for 304, and these product standards have some differences for different shapes of stainless steel.

Percentage dilution, chromium nickel ratio, microstructure, microhardness and tensile properties have been all found to be affected by the warmth enter. It was observed that welded pattern with warmth input of 0.4 kJ/mm possesses superior mechanical properties irrespective of type of filler wire used. Mechanical properties obtained through the use of 304L filler wire have been found to be better than these obtained using A240-304 stainless steel plates 308L filler wire, irrespective of heat input supplied during welding. The glorious combination of energy and corrosion resistance in duplex stainless steels is due to their strict composition management and microstructural steadiness. The ferrite–austenite ratio is often upset in DSS weld metals owing to the speedy cooling rates related to welding.

For a240 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance and value of 304 stainless steel.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements.
Specific requirements are stipulated by product standards.
The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.
This is why the industry calls this type of stainless steel 18/8 stainless steel.
In fact, the relevant product standards have very clear regulations on 304, and these product standards have some differences for different shapes of stainless steel.
Below are some common product standards and tests.

The ER446 weld metallic exhibited a ferritic-austenitic dual-part microstructure. Carbide precipitates enriched with Cr, Fe, and or Nb had been detected in all the three weld metals. The unmixed zone was observed on either side of the ERNiCr-3 weld metallic, while for the ER310 and ER446 weld metals it was shaped solely on one facet. The ER446 weld steel displayed the utmost hardness values, 221.9 ± 5 HV, with relatively giant fluctuations.
With precipitation hardened stainless steels, care must be taken to ensure that the unique mechanical properties usually are not compromised through the welding process. The variation of heat enter on microstructure and mechanical properties in gasoline metallic arc welding of ferritic stainless-steel using two different austenitic filler wires ER304L and ER308L have been discussed on this work.
- Measured values are correlated with the microstructure of base materials and heat-affected zone.
- Results show that heat during welding promotes recrystallisation of the microstructure, effect that is determined by the degree of deformation.
- In the current research, UNS S32205 duplex stainless-steel plates had been welded to AISI 316L chrome steel using pulsed fuel tungsten arc welding course of with three totally different filler metals; ER2594, ER312 and ER385.
- The effect of welding on native mechanical properties has been studied using a universal hardness tools, measuring universal and Vickers hardness, elastic and plastic energies and Young modulus.
In potentiostatic measurements pitting corrosion of spot-welded and induction-heated samples happens at decrease potentials than in the base supplies. In immersion exams the floor of the spot welds was not attacked but crevice corrosion was discovered between the sheets around the spot welds. The compositions and buildings of the heat-tinted oxides have been investigated by floor spectroscopy. The outcomes indicate the yellow, red and blue oxides to have a double-layered structure with an iron-wealthy and chromium-depleted outer layer and a much less iron and more chromium containing internal layer. A chromium-depleted layer was found within the base material underneath the yellow warmth-tinted oxide on an induction-heated sample. Significant amounts of copper contamination were discovered on the spot-weld surface near the weld edge.

In order to determine whether a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as one does not meet the requirements, it cannot be called 304 stainless steel.
