Hardening: This alloy does not harden by heat treating, just the same as the 304. Principal Design Features: The key feature of 321 stainless is its resistance higher resistance to extreme temperatures and conditions, when compared to 304. It contains titanium as a stabilizing element against chromium carbide formation.

Mar 29, 2005 · If this is not the case, it appears that AISI 321 stainless steel can be purchased in the solution annealed condition (no stabilization). According to ASM Handbooks Type 321 stainless steel is to be given stabilization HT only if in contact with highly corrosive media.
- The addition of Ti results in stabilization of the AISI Type 321 ss without the need for a separate stabilization heat treatment, which is separate...
- Practically speaking, you often don't need to worry about stabalizing 321. Either because your service temp is high enough to do it or because ther...
- Thanks Metengr, just another question. If all of the carbon at annealing temperature is dissolved into the austenitic matrix (this is what originat...
- The addition of Ti serves two purposes in austenitic stainless steel; besides forming TiC or Ti(C,N), it also increases mechanical properties at el...
- Thanks! This is something I wouldn't have found in books!
- Ti has higher affinity for carbon than chromium. Hence always TiC will be first formed to tie up any undissolved carbon.
- Not exactly always. If you are at the lower edge of the sensitization range there is not enough diffusion to allow Ti to tie up all of the C. The r...
- One reason for using 321SS is to aid in staving off polythionic stress corrosion cracking. If you're using it for that, or in environments suscepti...
- Another item to think about: Stabilization annealing of 347 stainless (Adds Columbium/Niobium instead of Titanium) apparently significantly reduces...

End results achievable through heat treatment include: 1. Hardening: Hardening makes the metal stronger. The material is first heated and soaked, and then plunged into oil or water for rapid cooling. Hardening can sometimes make the metal more brittle, which may then require the additional process of tempering. 2. Tempering: Tempering alleviates th...
Manufacturers usually employ an automated, CNC-controlled heat treatment line to perform multiple operations, and move the product through the various stations on a 24/7 basis. Equipment in the line may consist of: 1. Furnaces: Heat treatment furnaces are capable of achieving specified temperature and handling loads up to 1200 kilograms. 2. Carburi...
Impro uses heat treatment to process a variety of parts, such as bearings, valve, drive shaft, plate -butterfly, piston, flange, and diffuser. We also offer NADCAP-certified heat treatment processes for aerospace products to ensure these components meet the high dimensional accuracy and stringent strength and fatigue property requirements for aeros...
Alloy 321 cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices. Common Applications. Aerospace – piston engine manifolds; Chemical Processing; Expansion Joints; Food Processing – equipment and storage; Petroleum Refining – polythionic acid service
Hardening is the process by which heat treatments are employed to harden an alloy. Hardenability is the capability of an alloy to be hardened by heat treatment. There are several hardening treatments. Quench Hardening. For ferrous alloys, quench hardening is an austenite-forming (austenitizing) heat treatment, followed by cooling at a rate such ...
Nov 9, 2023 · Once a part, based on the right chemistry, is cast and cooled, it’s time to move the solid castings to the heat treatment ovens. Let’s take a look at how a hardening thermal process, known as phase transformation hardening, fortifies carbon and low alloy steels against stresses in the field.
Grade 304 or 316 austenitic stainless steel fasteners contain little carbon and therefore cannot be hardened by heat treatment. Certain martensitic stainless grades, such as ASTM A193 grades B6 and B5, can be hardened through a quench and temper heat treatment.
