Increased chromium for improved high temperature corrosion/oxidation resistance. 51CrV4 spring steel is a martensitic steel grade that is heat treated by quenching and tempering. Because of the large number of different steel grades, Table 1 includes only a few representatives typical of each group. In addition, there are hundreds of steel grades, and the chemical composition of different grades of steel varies. It is one of the most common stainless steels available, largely due to its excellent resistance to corrosion. 300 Series High Temp. Carbon content is low. [12] M35 M35 is similar to M2, but with 5% cobalt added. This expansion coefficient not only varies between steel grades, it also increases slightly with temperature. Resistant to SCC in petrochemical applications. Also discussed, but as a secondary consideration, are the corrosion-resistance qualities of stainless steels at elevated temperatures. High carbon steel is difficult to cut and bend which makes it ideal for tools. Here are some examples of continuous and intermittent stainless steel temperature limits: Grade 304. DIN17175/EN10216 standard specification. Background: High temperatures, 960 C and above, cause both grain growth and increased carbide dissolution along with chemical homogenization of the steel. Ferritic Stainless Steel This group of 400-series steels contains 10.5%-20% chromium for corrosion protection and resistance to scaling at high temperatures. The difference is somewhat uniform, but to make it distinguishable, all steel alloyed with higher than 8% of its weight of elements other than carbon and alloy is considered high-alloy steel. Coefficient of thermal expansion, = 12 x 10 -6 /C (in the ambient temperature range). Popular hot work tool steel grades include British Standards H13, H11, H21, Werkstoff grades 1.2344, 1.2343 & 1.2581. Other mechanical properties of structural steel that are important to the designer include: Modulus of elasticity, E = 210,000 N/mm. Mild steel has good hardness but as compared to stainless steel or grade 8 material, mild steel has less strength and corrosion resistance. For each one of the approved materials the usual Code establishes the allowable design stress at service temperature. Alloyed steels are harder, more durable and more resistant to corrosion. 2.
