Grade 202 stainless steel is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.
Grade 205 stainless steel is an austenitic standard grade. It is also referred to as AISI Type 205 Chromium-Manganese-Nickel steel. Grades such as the 205-series provide approximately 30% higher mechanical properties such as yield strength than the traditional 304-series.
Grade 301 is a cheaper alternative to the traditional high-nickel austenitic stainless steels such as grade 304. Grade 301L stainless steel is a low carbon steel which is ideal for improved ductility and when heavy sections are to be welded.
Grade 301 stainless steel strip is ideal for the manufacture of high strength room temperature springs, and when it is tempered to high strength levels, the steel maintains its ductility whether stress relieving is performed or not.
Zirconium is a refractory metal having excellent corrosion resistance, low thermal neutron cross section and good heat resistance. Zirconium alloys have higher thermal properties than other refractory alloys and high thermal conductivity than stainless steel alloys.
A tractor beam can be termed as an hypothetical device that is capable of attracting an object from a distance. It can also be defined as a hypothetical energy beam that can be used for controlling the movement of matter.

Grade 301 is an austenitic stainless steel that has a high work-hardening rate. Grade 301LN stainless steel is similar to grade 301L but with low carbon for improved ductility and welding of heavy sections.
Grade 308L stainless steel is a low carbon version of grade 308. It is particularly used to perform submerged arc welding of grade 304 stainless steel. It can also be used for welding the stabilized grades 321 and 347 in non-corrosive conditions.
Master alloys are semi-finished products that are used as raw materials in metal industries. These alloys are preferred over a pure metal because they are very economical and save energy. They are a pre-alloyed mixture of many alloying elements.
Master alloys are base metals which can be mixed with elements of higher percentage, and are added to a melt to achieve the desired result. They are formed in many shapes, and are also known as modifiers, hardeners, or grain refiners based on their applications.
