Stainless Steel F899 420B

Surgical instruments have been manufactured for a long time and there have been reports that surgeons and doctors in India have been using these instruments for thousands of years. In Greece and Rome, ingenious instruments were developed from bronze, iron and silver.

The surgical instrument is a tool or device specially designed to perform specific actions and desired effects during a surgical procedure or operation. Over time, various different types of surgical tools and instruments have been invented. Some surgical instruments are designed for use in general surgery, while others are designed for a specific procedure. Thus, the nomenclature of surgical instruments follows certain patterns, such as the description of the measures it performs (e.g. scalpel), the name of its inventor (the Kocher clamp), or a scientific compound related to the type of surgery.

In the twentieth century, with the growth of surgeries, it was necessary the urgent improvement, expansion and improvement of the arsenal of support of physicians in their surgeries, as well as the most suitable materials for their manufacture.

For many years, the availability of biometals suitable for the manufacture of implants and tools or surgical utensils was scarce. With this, stainless steel was used for the manufacture of surgical utensils.
And tooling.

Stainless steel is an alloy of iron and chromium, and can contain nickel, molybdenum and other elements that have physicochemical properties superior to common steels, with high resistance to atmospheric oxidation to
its main feature.

Stainless steel has great corrosion resistance, adequate mechanical strength, ease of cleaning/low surface roughness, ease of conformation, resistance to high and very low temperatures and its variations, surface finishes and varied shapes, modern and clean visual appeal and low maintenance cost. All these properties make stainless steel a very attractive material to satisfy various types of applications.

Within the needs imposed by the market, the F899 420B stainless steel was made available, used in abundance for different uses, such as the manufacture of cutlery materials, hospital, surgical and dental instruments, rulers, gauges, gears, axles, pins, bearings.
spheres, brake discs, among others. The classification of a stainless steel is related to the mechanical properties conferred on it in the
its development.

The ASTM F899 standard recommends 15 stainless steels of class 4 (martensitic) and 4 others of class 5 (for precipitation hardening) for different applications. Among all, the most common are grades F899 420B and 440C, of class 4 and XM 16, of class 5.

Sandinox has extensive experience in marketing a full range of materials, such as F899 420B Stainless Steel, also available in Barra 420B and Barra 420 format. Since 2006, ASTM has designated 420B, imported by Sandinox as 42010. This change is just a way the manufacturer found to differentiate its material. The 420B, also known as TrimRite®, is a material developed specifically for medical applications, following the ASTM F899 standard
UNS 42010.
