With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Type 304 is the most widely used austenitic (non-magnetic) stainless steel. It is also known as "18/8" stainless steel because of its composition, which includes 18 percent chromium and 8 percent nickel. Type 304 stainless steel has good forming and welding properties as well as strong corrosion resistance and strength.
The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 doesnt.
Stainless Steel 316 and 316L is a Chromium-Nickel stainless steel with added molybdenum to increase corrosion resistance and mechanical properties. Learn More 410 Stainless Steel Alloy
304 vs 316 Stainless Steel. The main difference between 304 vs 316 stainless steel is the composition and corrosion resistance, SS304 doesnt contain molybdenum while SS316 contains 2-3% molybdenum. The addition of molybdenum provides pitting resistance in phosphoric acid, acetic acid and dilute chloride solutions and provides corrosion resistance in sulfurous acid.
The addition of one or two percent molybdenum to ferritic stainless steels also significantly increases the corrosion resistance and the elevated temperature strength of these stainless steels. Fig 2: Adding 8% nickel to a ferritic chromium stainless steel makes an austenitic chromium-nickel stainless steel, for example Type 304 stainless steel.
Molybdenum grade stainless steels. Austenitic stainless steels account for almost 75% of all stainless steels used in the world; ferritic, about 25%; duplex (mixed austenite and ferrite), about 1%; and martensitic about 1%. Composition is the primary determinant of stainless steel microstructure.
This video demonstrate how to sort SUS304 and 316 by using Molybdenum test kit. Please email us at [email protected] agpindonesia.com for more detail Additional notes: 1) For series 200 stainless, the nickel best molybdenum in ss 304l
Duplex stainless steels can provide ferritic stainless steel properties while still maintaining a ductility and a toughness close to austenitic stainless steels. Typical Applications Sometimes the best way to find out what grade of stainless steel should be used is to see what has been used in the past.
The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts). I found the brochure Stainless Steel for Coastalbest molybdenum in ss 304l
Type 316 steel is an austenitic chromium-nickel stainless steel that contains between two and three percent molybdenum. The molybdenum content increases corrosion-resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures.
6% Moly Alloy is named after the 6% molybdenum content.Molybdenum is a silvery metal with the sixth highest melting point of any element. Consequently, it is often used in applications that involve extremely intense heat. 6% Moly Alloy also contains high levels of chromium and nitrogen, which also make them highly resistant to corrosion.

Stainless Steel: how problems arise and how to avoid Them Table 1. common Types of Stainless Steel stainless steel is a chromium alloy steel thats resistant to rusting and corrosion. The particular application for which stainless steel will be used determines the type and grade of stainless steel.
of stainless steel to pitting and crevice corrosion is indicated by its Pitting Resistance Equivalent number, or PRE, as shown in the table below. The PRE can be calculated from the composition as PRE = %Cr + 3.3 %Mo + 16 %N Clearly grades high in the alloying elements chromium and especially molybdenum and nitrogen are more resistant. This is
As a result, molybdenum bearing grades, such as 316/L, are not particularly useful in nitric acid service. Duplex alloy 2205 appears to offer no advantage over 304L in pure acid. Duplex and superduplex alloys may offer some advantage in acid containing metal ions, such as pickling solutions.
Use 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to 304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309.

Stainless steel 316L. 304 becomes 316L when an alloy called Molybdenum is added to the mix. Molybdenum is the Super Man of the alloy world. It increases the strength of stainless steel and also makes it more durable in harsh and corrosive environments.
Outwardly, 304 stainless steel and 316 stainless steel look very similar. Both are non-magnetic, austenitic, and non-hardenable through heat treatment. Each of these stainless steel grades will resists corrosion, are quite durable, and are easily formed and fabricated. The difference in their structure is primarily the addition of molybdenum to best molybdenum in ss 304l

These two Stainless Steels are very similar in their mechanical properties and are among most widely used austenitic stainless steels (304 edging out 316 for most prevalent). Their chemical makeups are slightly different: SAE 304 SS Also known as A2 Stainless or 18/8 for its composition of 18% chromium and 8% nickel.
Electrolyte for Detection of Molybdenum for Checking Stainless Steel 304 & 316 Grade Moly Detector Solution. Stainless steel grades AISI 304 and AISI 316 grades are widely used in industry. Corrosion resistance of AISI 304 grade due to the presence of MOLYBDENUM in AISI 316 grade. Put one drop of chemical on the test metal.
What is the Difference Between 304 and 304L Stainless Steel? When it comes to variations between 304 and 304L stainless steel, an essential thing to note is the latters greater immunity to intergranular corrosion. Intergranular corrosion is the cracking that can occur along grain boundaries of steel in the presence of tensile stress.

The problem is that they are a mix of 304 and 316. There is a test that I know of. A chemical is applied to 316.
304 and 304L Stainless Steel Type 304 Stainless Steel is the most widely used of the austenitic (chromium/nickel) stainless steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work.

The letter L after a stainless steel type indicates low carbon (as in 304L). The carbon is kept to .03% or under to avoid carbide precipitation. Carbon in steel when heated to temperatures in what is called the critical range (800 degrees F to 1600 degrees F) precipitates out, combines with the chromium and gathers on the grain boundaries.
