Recommended filler rods and electrodes for chrome steel 304 is grade 308 stainless-steel. Grade 321 could also be used if submit-weld warmth remedy isn’t possible.


We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

The steel is modified for machining and is available in a variety of profiles and dimensions. The steel is commonly used for particulars inside building and construction, machining business. There are two European steels of the ‘304L’ type, 1.4306 and 1.4307.

Grade 304/304L is essentially the most extensively used business grade of stainless-steel supplied into numerous industry sectors. It has excellent corrosion resistance in odd atmospheric circumstances, it is easily machined and can be simple to weld. The steel grade 1.4307 (additionally known as ASTM 304/ 304L – SS2333) is a basic function stainless steel, called 18-8-steel, with good corrosion resistant, impression strength and formability. The steel has improved machinability by, MAXIVAL®, and it’s suitable for manufacturing of corrosion resistant products by machining. It has good corrosion resistance to uniform corrosion and to many barely corrosive organic and inorganic chemical substances.

  • Grade 304/304L is probably the most extensively used business grade of stainless steel equipped into numerous business sectors.
  • The steel grade 1.4307 (additionally known as ASTM 304/ 304L – SS2333) is a common function chrome steel, known as 18-8-steel, with good corrosion resistant, impact strength and formability.
  • It has good corrosion resistance to uniform corrosion and to many barely corrosive natural and inorganic chemical substances.
  • It has excellent corrosion resistance in strange atmospheric circumstances, it’s simply machined and is also simple to weld.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.

Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean

Higher chromium content imparts further corrosion resistance. Nickel is primarily used to attain a selected microstructure. In addition, it has a useful effect on mechanical properties and sure kinds of corrosion. In extra corrosive environments such as a marine setting, or an environment where larger chloride and chlorine content is a factor, a higher spec grade corresponding to 316/316L or a Duplex grade may be a better choice.

1.4307 is a chrome steel which normally is more difficult to machine than ordinary carbon steels, but because of MAXIVAL® it has improved machinability. It can be readily welded by a full range of typical welding methods. 1.4307 can’t be hardened by heat treatment, however it may be hardened by cold working. This may end up if the steel is held in a temperature range 450 to 850°C for periods of several minutes, depending on the temperature and subsequently uncovered to aggressive corrosive environments. Fusion welding efficiency for sort 304 stainless steel is superb both with and without fillers.

Since this materials is alloyed in such a way to enhance machinability, the quantity of floor oxides on the welded beads might be higher in comparison with standard 304/304L steels. This might result in arc instability during TIG/GTAW welding, particularly welding without filer materials. However, the welding habits of this materials is identical as for normal 304/304L steels when welding with filler materials.

This could end result within the ‘normal’ carbon types needing extra pressure to carry them in place once fitted-up for welding, with more of a bent to spring-back if not properly held in place. Fabrication strategies, like forging, that contain hot working should happen after uniform heating to °C.

There doesn’t seem to be a clear purpose for this and the variations are in all probability related to the lower energy of the low carbon type. The low carbon kind may be simpler to shape and type, which in flip can also affect the degrees of residual stress left the steel after is forming and becoming up for welding.
