Grade 316, and grade 304, may suffer stress corrosion cracking in solutions containing chloride ions at temperatures over about 60¡ãC. Stress corrosion cracking should be considered for all corrosion services where the corrosive liquid may contain chloride.

Alloy 254 SMO contains high levels of chromium, molybdenum and nitrogen and is often used in high chloride environments such as brackish water, sea water, pulp mill bleach plants and other chloride process streams.

304 stainless steel plate is comprised of at most 0.08% carbon. 304 stainless steel plate also includes at most 2.0% manganese and 0.75% silicon.

Austenitic stainless steel 304 L is favored by most buyers for its excellent weldability and is a low carbon version of the very popular alloy 304. Stainless steel 304L pipe fittings tend to be resistant to intergranular corrosion since the reduction in carbon means the alloy is not sensitized by grain boundary precipitates.

We pride ourselves in our design and fabrication process of Stainless Steel 309 Hex Head Bolts and Stainless Steel 309 Square Head Bolts that meets the needs and specifications of our clients.

Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Although type 316 alloys are more resistant to SCC than 18Cr-8 Ni alloys due to their molybdenum content, they are still susceptible. Conditions that produce SCC are: (1) the presence of halide ions (usually chloride ions), (2) residual tensile stress, and (3) temperatures in excess of about 120¡ãF (49¡ãC).

904L fasteners come in different types such as bolts, studs, nuts, washers, socket head caps, screws, clamps and more.

The A182 F310 Flange is meant for forged or rolled flanges that have threads on them to be joint to the pipes with male threads. The threaded flanges are useful when the welding or bolting methods are not preferable.

SS 304 ASME 16.5 forged Flange
Featuring 304 stainless steel for very good corrosion resistance, this GRAINGER APPROVED weld neck flange can be attached to a system via a circumferential weld at the neck. The welded area can be easily examined by radiography. Matched pipe and flange bore reduces turbulence and erosion inside the pipeline. Flange is excellent for use in your critical applications and is ideal for use with air, water, oil, natural gas, and steam.

There are hundreds of different grades of stainless steel on the market. Each of these unique stainless steel formulations provides a degree of corrosion resistance that exceeds that of ordinary steel. The existence of these stainless steel variants can cause some confusion – especially when the two stainless steel alloys are nearly identical in name and formula. This is the case with 304 and 304L stainless steel.

After hot working, anneal the tube by heat to 1725 and 1850 for at least half an hour to match the inch thickness observed by water quench. Intergranular corrosion (IGC) in pipe fittings, also known as intergranular corrosion (IGA), is a form of corrosion in which the crystallite boundaries of fabrics are particularly susceptible to corrosion. UNS S30403 fittings can be properly hot formed with forces very similar to those required to pass through austenitic steels.

304l pipe has good oxidation resistance in intermittent duty up to 870¡ãC and continuous duty up to 925¡ãC. However, continuous use at 425-860¡ãC is not recommended. In this case, 304L is recommended because of its resistance to carbide precipitation. Where high strength is required at temperatures above 500¡ãC and up to 800¡ãC, Grade 304H is recommended. This material will remain resistant to water corrosion.

316L stainless steel possesses less carbon and molybdenum than typical 316 steel, which gives the two alloys different characteristics.

UNS S31603 Elbow also has excellent resistance to pitting corrosion and soaring tensile strength. They are machined to have tough and strong chip characteristics. SS 316L 45 Degree Elbow is also considered to be more resistant to general corrosion and pitting than normal Nichrome.

Grade F22 is a low alloy steel containing nominally 2.25% Chromium. The alloy is widely used in the oil patch wellhead applications for connectors, hangers and block valves. Hardness levels up to 22 HRC are approved to NACE MR0175. The grade is often used as the base metal for clad components.
If supplied to ASTM A182 in the normalised and tempered condition, the 0.2% Proof Stress minimum is 30 KSI.Grade 22 of the ASTM A182 alloy steel is a low-alloy steel that contains 2.25% chromium. Often used as base metal for clad components, the F22 is also used in the oil patch wellhead applications for products such as hangers, connectors, and block valves, among others.

Most iron-based metals react with water to produce the reddish iron oxide known better as rust. The oxygen atoms in the water pulls iron off of the base metal to form the porous rust structure with no real strength.

La tuberia 254 SMO a menudo se usa como reemplazo de componentes criticos de estructuras grandes donde el tipo 316L o 317L falla debido a picaduras o agrietamiento por corrosion bajo tension de cloruro, la tuberia 254 SMO puede soportar los mismos entornos corrosivos.

Stainless steel 1.4529 HCR is characterized by a high resistance to localized corrosion phenomena such as crevice corrosion, pitting corrosion or chlorine-induced stress corrosion cracking. It also exhibits excellent mechanical properties and can be used over a wide temperature range. It has excellent elasticity and abrasion resistance in contact with sulfuric or phosphoric acid, or chlorides and salts.

Fully austenitic welds are more prone to cracking during welding. For this reason, Type 316 and Type 316L “matching” filler metals are formulated to cure with a small amount of ferrite in the microstructure to minimize cracking susceptibility.

Our 347 stainless steel bars are extremely resistant to prolonged heat and corrosion, making them ideal for power generation, engines, welded fabrication and other high temperature applications.
