All connective tissues, including the loose variety, are composed of two basic components: intercellular matrix and cells. The types and relative proportions of each determine the kind of connective tissue. The intercellular matrix of loose connective tissue is composed of various fibers and ground substance.A. Connective tissue fibers. There are three types of fibers in the intercellular matrix of connective tissue: (1) collagen fibers, (2) reticular fibers, and (3) elastic fibers.Collagen fibers. The most prevalent protein in the body is collagen.ll connective tissues, including the loose variety, are composed of two basic components: intercellular matrix and cells.

AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint.The alloy can be hardened by heat treatment.rincipal Features.

The values shown. are based upon a corrosion allowance of 0.05 inches for sizes 1 and smaller. For sizes 1 1/4 and. larger, a corrosion allowance of 0.065 inches is used. *** Upon prolonged exposure to temperatures about 775o the carbide phase of carbon steel may be. converted to graphite. For other applications refer to appropriate section of B31 Code for Pressure. Piping.
