The 316 stainless steel round rod has an unpolished (mill) surface, has been annealed, meets SAE Aerospace Material Specifications AMS 5648 specifications, and has a standard tolerance. The 316 stainless steel grade provides better corrosion resistance than general-purpose 304 stainless steel, especially in marine environments, due to higher nickel content and the addition of molybdenum. An austenitic stainless steel, 316 is typically nonmagnetic and can be cold worked to increase its hardness and strength while maintaining most of its formability. The material has been annealed, a method of heating and cooling metal to modify its properties, such as increasing its formability and toughness or decreasing its strength, after it has been shaped.
Stainless steel is an iron alloy with resistance to staining and rusting in many environments where steel would typically degrade. The chemical composition of each grade creates a grain structure that falls into one of five classes: austenitic, duplex, ferritic, martensitic, and precipitation hardening. The austenitic class contains the most formable, weldable, and corrosion-resistant stainless steel grades, but they cannot be heat treated. The duplex class offers high resistance to pitting and chloride stress corrosion cracking. Duplex grades are heat treatable and roughly twice as strong as austenitic grades. The ferritic class contains moderately formable and corrosion-resistant grades compared to other stainless steel classes, but they cannot be heat treated. The martensitic class includes some of the hardest and strongest stainless steel grades that also offer mild corrosion resistance, high hardness, and good formability. Martensitic grades can be heat treated. The precipitation-hardening (PH) class can be heat treated after fabrication to achieve some of the highest hardness ratings in stainless steel.
Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded. Magnetism characterizes how much the material is repelled by or attracted to a magnet.

The final product, cat-whisker TV antenna (on steroids) works *awesome*. Do not try this at home.

Not much to review. Exactly as described in the title / description. I would buy again as it is what I needed.Published on December 15, 2013 by apharc
Hi quality stainless and machined well. I bought this for a pin for a workbench and it it just as described.Published on October 23, 2013 by AndrewM
Used this to make a shaft for a small mixer (the old shaft had been lost). This stainless steel rod milled well and works nicely.Published on May 18, 2013 by Steven C Chiesa
It is hard. It is round. It is long. It is stainless steel. Now get your mind out of the gutterPublished on May 1, 2013 by DAVID A CAVALLARO
These rods showed up and met the specs. They were not bent or have any other noticeable defect. I am using them to build a multi pad model rocket launcher.Published on April 19, 2013 by Daniel C. Clark
