Stainless Steel Machining Characteristics
Stainless Steel Alloy 304
.Tolerance +/-0.01
.Material Cost Factor: 3.7
.Machining Cost Factor 5.0
The stainless steel 304 alloy is designed for better weld-ability a form-ability and is slightly more corrosion resistant. Alloy 304 is commonly machined for applications needing more form-ability or weld-ability .
Stainless Steel Alloy 303
.Tolerance +/-0.01
.Material Cost Factor: 4.5
.Machining Cost Factor 2.7
Stainless steel alloy 303 is a non-magnetic alloy designed for machining. It is commonly machined into components for automotive, aerospace, or medical instruments,electronic hardware, or many other applications requiring corrosion resistant components.
Stainless Steel Alloy 316
.Tolerance +/-0.01
.Material Cost Factor: 4.3
.Machining Cost Factor 5.6
316 stainless steel is designed for better corrosion resistance .Alloy 316 is often machined for medical implants, surgical instruments, and aerospace parts.
Stainless Steel Alloy 416
.Tolerance +/-0.01
.Material Cost Factor: 3.8
.Machining Cost Factor 2.6
Stainless Steel 416 is less corrosion resistant than the 300 series alloy ,but it can be heat treated. Machined 416 parts are commonly used where less corrosion resistance is needed,but more hardness is required for a lower cost .
Stainless Steel Alloy 440C
.Tolerance +/-0.01
.Material Cost Factor: 5.9
.Machining Cost Factor 5.0
440C stainless steel alloy is high in carbon and can be hardened to HRC60. Customers choose alloy 440C for applications that require the highest hardness in stainless steel.
Stainless Steel Alloy 17-4 PH
.Tolerance +/-0.01
.Material Cost Factor: 4.4
.Machining Cost Factor 5.0
Stainless steel alloy 17-4 PH is very corrosion resistance and high-heat treatable. Rayland machines 17-4 PH for medical and aerospace applications that require excellent corrosion resistance and hardness .
Stainless Steel Passivation
There are many kinds of stainless steel surface treatment technology, such as electroplating, anode oxidation, sand blasting ,powder coating, painting, passivation ,acid pickling, oil removal ,rust removal, etc . Of them ,the commonest surface treatment is passivation.
What is Stainless Steel Passivation?
Stainless Passivation is the process by which stainless steel will spontaneously form a chemically inactive surface when exposed to air or other oxygen-containing environment. Some important facts to know when considering passivating stainless steel :
- Steels containing more than 11% Chromium are capable of forming an invisible, inert or passive, self-repairing oxide film on their surface. It is this passive layer that gives stainless steels their corrosion resistance.
- If a stainless steel surface is scratched, then more Chromium is exposed which reacts with oxygen allowing the passive layer to reform. However, if a particle of carbon steel is embedded in the scratch then the passive layer cannot reform and corrosion will occur when the metal is wetted or exposed to a corrosive environment.
- Stainless steel passivation is the chemical treatment of a stainless steel surface with a mild oxidant such as citric acid passivation solution. This process is to accelerate the process noted above in No. 1.
- Passivating stainless steel is the removal of exogenous iron or iron compounds from the surface by means of a chemical dissolution, most typically by a treatment with an citric acid passivation solution that will remove the surface contamination but will not significantly affect the stainless steel itself.
- · Passivation also is accomplished by stainless steel electropolishing . Electropolishing is an elextrochemical process that is a super passivator of stainless and results in a more passive surface than the other methods mentioned above.
This last step is necessary because during handling and processing such as rolling, forming, machining, pressing, tumbling, and lapping, particles of iron or tool steel or abrasive particles may be embedded in or smeared on or into the surfaces of stainless steel components. If allowed to remain, these particles may corrode and produce rust spots on the stainless steel. This is due to the formation of a galvanic couple between two dissimilar metals that can promote a corrosive reaction. To dissolve the embedded or smeared iron and prevent this condition, as well as restore the original corrosion-resistant surface, semi-finished or finished parts are given a 'passivation' treatment.
How Stainless Steel is Passivated
The passivation of stainless steel is performed when free iron, oxide scale, rust, iron particles, metal chips or other nonvolatile deposits might adversely affect the metallurgical or sanitary condition or stability of the surface, the mechanical operation of a part, component or system, or contaminate the process fluid. Stainless steel is passivated through a cleaning cycle to remove oils, grease, compounds, lubricants, and residue followed by a nitric or a citric acid bath or a by an oxidant that removes free iron and contaminates.
Passivation is performed on clean stainless steel, providing the surface has been thoroughly cleaned or descaled. Since the term "passivation" is used to describe distinctly different operations or processes relating to stainless steels, it is necessary to define precisely what is meant by passivation.
Stainless Passivation Specifications in use :
- ASTM A 967, Chemical Passivation Treatments for Stainless Steel Parts
- ASTM A 380, Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment and Systems
- Federal Specification QQ-P-35C, Passivation Treatments for Corrosion Resistant Steels
- ASTM B 912, Passivation of Stainless Steels Using Electropolishing
