Cesium is silvery gold in appearance, soft and ductile by nature. It is the most alkaline and the most electronegative element. It is in the liquid state at room temperature.
Lead is a chemical element with Pb as its symbol. It belongs to group 14, periodic number 6 of the periodic table. Its atomic number is 82.
Lithium is a chemical element with Li as its symbol. It belongs to group 1, period 2 of the periodic table. Its atomic number is 3. It is a part of the alkali metal group of chemical elements.
Manganese is a pinkish-gray, chemically active element with Mn as its symbol. It belongs to group 7, periodic number 4 of the periodic table. Its atomic number is 25.
Molybdenum is a chemical element with Mo as its symbol. It belongs to group 6, periodic number 5 of the periodic table. Its atomic number is 42, and has a Mohs hardness of 5.5.
Recently it seems that not a day goes by without someone announcing a new innovation in 3D printing. From guns to full scale houses, the items that can be created via additive manufacturing seem potentially limitless.

The presence of large amounts of chromium in stainless steel alloys is what provides it the high level of corrosion resistance than other steels. Stainless steels are classified into martensitic, ferritic and austenitic based on their crystalline structure.
Tungsten is a good carbide former that increases temperature and red hardness, prevents gain growth and improves toughness. It is a steel gray metal used in high speed steels and hot forming tool steels.
Chromium hot-work tool steels are designated as group H steels according to the AISI classification system. This series of steels start from H1 to H19. The most commonly used chromium hot-work steels are H11, H12, and H13, which can be air hardened in 150 mm thick sections.
