Stainless steels are iron-base alloys containing 10.5% or more chromium. They have been used for many industrial, architectural, chemical, and consumer applications for over a half century. Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are well over 100 stainless steel alloys.

400 Series Stainless - Penn Stainless

400 Series Stainless. The 400 series group of stainless steels has an 11 percent chromium and 1-percent manganese increase, above the 300 series group. The 400 series is susceptible to rust and corrosion under some conditions. Heat-treating will harden the 400 series. The 400 series of stainless steels have higher carbon content, giving it a martensitic crystalline structure. 410 Stainless Steel - Penn StainlessAlloy 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. Alloy 410 contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild

Difference between 300 and 400 Series Stainless Steel

The absence of nickel in their chemistry is what makes all stainless steel alloys under the 400 series cost less, in comparison to 300 series. And as nickel is a commodity metal, its price remains volatile. Fluctuating prices almost always lead up to an upcharge in the cost of using nickel Effect of Thermal Aging in Stainless Steel Welds:2 Year a comparative study on the thermal aging effects in stainless steel cast and weld alloys. The first step of the study was production of weld overlays on steel substrates:experimental weld plates were fabricated by gas tungsten arc welding (GTAW) method using ER316L and ER308L (low carbon grade) and ER347 (niobium stabilized grade) welding wires.

Electralloy - Nitronic®

Nitronic® stainless steels are austenitic, high-strength, corrosion-resistant products that provide higher-performance alternatives to many conventional 300 and 400 Series stainless steels. Electralloy is North America's exclusive licensed producer of all Nitronic® bar, billet, coil rod, master alloy pigs and ingot products as well as Ferritic Stainless Steels Stainless Steel TypesFerritic stainless steels can be welded using the common fusion and resistance welding techniques. The metallurgical structure of the ferritic alloys imposes some restrictions on welding. The unstabilized grades can form martensite in the heat affected zone leading to a loss of ductility.

Properties of Stainless Steel and how to weld

They are classified as austenitic, and are hardenable only by cold working methods. These grades of stainless have chromium (approx. 18 to 30%) and nickel (approx. 6 to 20%) as their major alloying additions. Type 304 (also known as 18-8) is the most widely used alloy of all stainless steels. 301 An austenitic stainless steel. Selecting Filler Metals for Stainless Steel WeldingFor welding 304 to itself, use a 308/308L filler metal that offers a matching chemistry. Additionally, 309/309L is recommended for welding 304 to carbon steel or for the barrier layer for overlays on carbon steel. The 316/316L types of stainless steels contain molybdenum (Mo) and are commonly used in more corrosive applications than the 304 type.

Typical Applications. The extra low carbon alloy is specifically indicated for AISI 309Mo type alloys, but is also ideal for joining mild/low alloy steel to a range of 300 and 400 series stainless steels.

Study of Austenitic Stainless Steel Welded With Low Alloy

to weld an austenitic stainless steel manifold. It is the conventional prac- tice to weld the austenitic stainless steels with austenitic stainless filler metal, usually of the same or similar composition. For example, AISI* type 316 stainless steel is often welded with 316L filler metal ("L" denotes low carbon, 0.03% maximum carbon content). Survey Question:Does everyone use preheat welding 410SS?Sep 26, 2009 · OBEWAN, To give an answer to your question:We weld from 405 t0 422 to mild steel, 410 and CoMo on a regular bases with out that much preheat using mostly INCO 82 and on rare occasion 309L. We try to use preheat but all the welding is manual with extreamly difficult access and visability (you almost have stick youre head up against the work to

Weldability of Stainless Steel The Metal Press by

The dozens of alloy variants make welding stainless steel more complicated than welding traditional carbon steel. However, while stainless alloys were once considered a major challenge to weld, today they are described as different as opposed to difficult among most welders. Stainless Steels are high alloy steels containing a Welding Guidelines - Electron Beam Welding Laser Nickel alloys Most weld well Platinum Weldable PH Steels All weld well with special techniques. Silver Weldable Stainless Steel 300 series - welds well, except 303and 347. Note that 304 is preferable to 316. 400 series welds somewhat brittle. Steel-Low Carbon Below 0.2% carbon is weldable Steel

Welding of Ferritic / Martensitic Stainless Steels - TWI

The ferritic stainless steels are generally welded in thin sections. Most are less than 6mm in thickness where any loss of toughness is less significant. Most of the common arc welding processes are used although it is regarded as good practice to limit heat input with these steels to minimise grain growth (1kj/mm heat input and a maximum Welding of Steels ::Total Materia Article

Martensitic (high-strength iron/chromium). Wear-resistant, but less corrosion-resistant. "Most common methods of welding, can be successfully employed with this alloy. To reduce the chance of cracking, it is advisable to preheat the workpiece to 350-500 F. Post-weld annealing is recommended to reattain maximum ductility.

    Welding 400 series stainless - American Welding Society

    May 17, 2003 · As you know stainless steels are susceptible to precipitation of chromium carbides in the range of 400 to 800C. On the other hand martensitic stainless steels must be preheated before welding and if carbon content be high enough they must be PWHT after welding. Certainly, because of preheating and PWHT chromium carbides will be precipitated.
