An austenitic chromium-nickel-silicon grade, 253 MA® offers outstanding strength and unrivalled heat resistance. 253 MA® was developed over 30 years ago, when the need for a heat resistant stainless steel with high strength and good oxidation resistance was required in the industry. 303 stainless steel plate - UNS S30300 - For cutting and Hardness. (max) 202 (HBN) 303 and 304 have similar chemistry and both are iron alloys, however Alloy 303 was purposefully developed for ease of machining. The additional sulfur present in 303 assists in breaking up turnings which reduces drag on the cutting tool and increases machining speeds.
Alloy 303 (UNS S30300) is a non-magnetic, austenitic, free-machining stainless steel that is a modification of the basic 10% chromium -8% nickel stainless steel specially designed to exhibit improved machinability while maintaining good mechanical and corrosion-resistant properties. Duplex Stainless Steel Fabrication Mechanical Properties Cutting Forming Machining Welding Post-Fabrication Cleaning. 4 Cutting, Mechanical Shearing More force and heavier equipment will be required to Grade °C °F 2205 1100 to 950 2010 to 1740 Free-Cutting Brass (UNS C36000) for Automatic Screw

Free-Cutting Brass, which many people know by it's traditional name, CDA Alloy 360, is the most important commercial copper alloy, surpassing all but copper itself in terms of annual consumption. Exact quantities are difficult to calculate, but over 600 million pounds of Free-Cutting Brass are consumed in the U.S. each year. Despite this large usage, brass is underutilized as an automatic screw machine feedstock. Perhaps ten times more leadeAISI 202 (S20200) Stainless Steel ::MakeItFromMay 30, 2020 · AISI 202 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 202 is the AISI designation for this material. S20200 is the UNS number. Additionally, the British Standard (BS) designation is 284S16. It has a moderately low base cost among wrought austenitic stainless steels.
May 18, 2005 · Type 304 is the most versatile and widely used stainless steel. 304 stainless steel is an austenitic grade that can be severely deep drawn. The properties, applications and fabrication details are provided for 304 stainless steel. Heat input and shielding gas effects on the microstructure Sep 01, 2020 · AISI 202 grade austenitic stainless steel plate in a cold worked condition with a thickness of 2 mm was used as the base metal and a 2.6 mm diameter grade AISI 316 L austenitic stainless steel filler metal were used in this study. Commercial grade materials were used in both cases. Machinability Study of AISI 316 Grade Austenitic Grade 316 is the standard molybdenum-bearing grade. Molybdenum gives 316 better corrosion resistance properties than crevice corrosion in chloride environment. Mechanical properties (d) Physical properties (e) Cutting conditions The criteria for judging machinability may be :(a) Tool life (b) Cutting force (c) Surface finish
The processing properties of the material are improved by adding sulfur. 420 stainless steel Blade grade martensitic steel, the earliest stainless steel, similar to Brinell high chromium steel. It is also used for surgical cutting tools, which can be very bright. 430 stainless steel ium Grades and Relative Properties - Rolled Alloys, Inc.Grade 12 has a slightly higher minimum mechanical property requirement than that of Grade 3 yet slightly lower than that of Grade 4. What separates Grade 12 from all of the CP grades is that it contains .6-.9% nickel content and .2-.4% molybdenum. The table below shows the chemistry and properties of these almost CP alloys.Difference between Stainless Steel grade 304 and 202. Can Oct 07, 2008 · The major differences between 202 and 304 stainless steels are in the nickel and chromium contents. 202 has 16-18% chromium and 0.5-4.0% nickel, whilst 304 has 18-20% chromium and 8-10.5% nickel. There are other minor differences in the amount of carbon (0.08% in 304 and 0.12% in 202), manganese (2% in 304 and 5.5-7.5% in 202), as well as slight differences in the silicon,
