The ductilebrittle transition is exhibited in bcc metals, such as low carbon steel, which become brittle at low temperature or at very high strain rates. FCC metals, however, generally remain ductile at low temperatures. In metals, plastic deformation at room temperature occurs by dislocation motion.

The structure of 310 stainless steel was found to be austenite, and did not vary over the range of conditions studied. On the contrary, the structures of types 308 and 312 steels were very sensitive to the cooling rates and solidification conditions.
Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. The following datasheet gives an overview of grade 440C stainless steel. Chemical Composition. The chemical composition of grade 440C stainless steel is outlined in the following table.
Comparison of structural design in stainless steel and carbon steel Stressstrain behaviour of carbon steel and stainless steel. The stressstrain behaviour of stainless steel differs from that of carbon steels in a number of respects. The most important difference is in the shape of the stressstrain curve.
Any structural steel components that in the opinion of the Engineer have been damaged or otherwise rendered useless by the improper handling by the Contractor shall be replaced by the Contractor at his own expense. If the structural steel components are stored on site, the requirements of the Specifications for Supply and Fabrication of Structural Steel, Clause shall apply. Bearing Areas .1 Grout Pads

Surgical instruments, food processing parts and mold components are typically made from 420 stainless steel. 440C stainless steel (the "C" denotes a higher carbon content) is wellsuited for tool and die applications in the food processing industry due to its higher hardness. Ferritic stainless steels cannot be hardened by heat treatment. However, they display maximum ductility, impact toughness and .
Stainless steela ahow good resistance to all concentrations of ammonia and ammonium hydroxide solutions up to the boiling point. Above the at mospheric boiling point, the corrosion rate may increase rapidly, particu larly in anhydrous ammonia. In liquid omiironis contuining ummonium

Structural Angle is a steel bar that has an Lshaped cross section. It is a piece of structural iron or steel in the form of a 90 degree angle. It is ideal for all structural applications, general fabrication and repairs. This item can have equal sized legs (or flanges); this is typically known as equal leg angle.

Fig. 1 — Effect of nickel on the structure of a cast stainless steel containing 14% Cr simulate the microstructures of welds and castings, charges cut from two welds and a 7500 lb stainless casting were remelted and cast as small pins. As Table 1 shows, there was a good correlation between the delta ferrite contents of the three pins and those of
Stainless steel structures in swimming pools are known to be prone to SCC. The use of standard austenitic stainless steels like 304 and 316 is forbidden in this application. The best steels to use for this purpose are the high nickel austenitic steels such as the 6% Mo grades.
