Speeds & Feeds in stainless steel - Practical MachinistFeb 18, 2007 · I've been working with surgical grade stainless steel on Star and Citizen swiss style lathes. We mainly use 17-4, 455, 440A, and 440C. Recently I have started programming with Partmaker CAD/CAM offline. Without being at the lathe when these programs are setup and ran, I am having trouble optimizing these programs.

What is the difference between 17-4 and 316L stainless steel?

The numbers 17-4 refer to its composition: 17% chromium and 4% nickel. It also can include between 3 and 5% copper. It is the most common material used in the production of Setras variable capacitance transducers. Its durability and mechanical properties make 17-4 SS the ideal choice for transducers in both HVAC and general industrial applications. 316L Stainless Steel. 316L stainless steel is defined What is a 410 filler?Type 410 filler is used to weld types 402, 410, 414 and 420 steels. Austenitic types 308, 309 and 310 are also used to weld martensitic steels to themselves or dissimilar metals. Precipitation-hardening stainless steels contain both chromium and nickel. These metals provide a combination of the properties of martensitic and austenitic grades.See all results for this questionWhat is 455 Stainless steel?Custom 455 stainless represents a significant advancement in the area of precipitation hardening stainless steels. It should be considered where simplicity of heat treatment, ease of fabrication, high strength and corrosion resistance are required in combination.See all results for this question

What is 440 stainless steel?

Grade 440C stainless steel is pre-heated at 760°C (1400°F). Temperature can be increased up to 1038-1204°C (1900-2200°F). It should not be heated below 927°C (1700°F). It is then slowly cooled at room temperature and fully annealed. Grade 440C stainless steel is slightly cold workable using common practices.See all results for this questionWhat is 17 4 stainless steel?17-4 Stainless Steel Properties | KVA Stainless. Type 17-4 is the most common grade of martensitic precipitation hardenable (PH) alloys. 17-4 provides an outstanding combination of high strength, good mechanical properties at temperatures up to 600°F (316°C), and short-duration, low-temperature heat treatments that minimize warpage and scaling.See all results for this questionWeldability of Stainless Steel | The Metal Press by ss 455 ss 440 17 4We carry: 410, 420, 440.

Slaying Stainless Steel: Machining Guide - In The Loupe

Stainless steels are high-alloy steels with superior corrosion resistance to carbon and low-alloy steels. This is largely due to their high chromium content, with most grades of stainless steel alloys containing at least 10% of the element. Stainless steel can be broken out into one of five categories: Austenitic, Ferritic, Martensitic, Precipitation Hardened (PH), and Duplex. In each category, there is one basic, general purpose alloy. From there, small changes in composition are made to the base in order to create specifiSee more on harveyperformance ss 455 ss 440 17 4Select Stainless Steel of Hardness and Corrosion ss 455 ss 440 17 4Stainless Steel for Hardness and Corrosion Resistance<,Stainless Steel Tube ss 455 ss 440 17 4 Except for the 440 family of stainless steels, ss 455 ss 440 17 4 17-4 PH 630 UNS S17400 Stainless Steel 253MA S30815 Stainless Steel Tube S31254 254 SMO Pipe S31803 Stainless Steel 2205 Duplex Pipe TubingMaterial Safety Data Sheets - YardeMaterial Safety Data Sheets Issue Date: 08/19/2010 MSDS #: SS SECTION 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION Product Name: Stainless Steel Grades: 303, 304-304L, 316-316L, 321, 347, 410, 416, 420, 440, 455 Synonyms: None Yarde Metals, Inc., 45 Newell Street, Southington, CT 06489 1-800-(800) 444-9494 or Contact Your Nearest Yarde Metals Office
