ASTM A320

Scope Originally approved in 1948, the ASTM A320 specification covers alloy steel and stainless steel bolting materials for low temperature service. This standard covers rolled, forged, or strain hardened bars, bolts, screws, studs, and stud bolts used for pressure vessels, valves, flanges, and fittings. Like the ASTM A193 specification, unless otherwise specified, the 8UN thread series is specified on fastener larger than 1” in diameter. Below is a basic summary of a few of the common grades within the ASTM A320 specification. A number of other less common grades of ASTM A320 exist, but not covered in the description below.

    Product Description

    Pulsar by Seiko Holdings Corporation.

    A spectacular breakthrough

    Pulsar was born in an age of optimism. In the 1970′s, everything seemed achievable through the rapidly growing technological expertise at the world’s fingertips. Space flight had been converted from dream to reality, computer science was developing at break neck speed and electronics seemed to deliver new advances every day. Pulsar symbolized the age. It was new and it was bold, it was surprising and it was different. Pulsar, the world’s first electronic digital watch, created a sensation when it was unveiled in New York in 1972 and it changed the world’s perception of time.

    A tradition of difference

    When the brand was taken into the Seiko Corporation in 1980, it brought further surprises to the world; the first calculator watch in 1980 and the first all-quartz watch line in 1981 were among its industry-leading achievements. And throughout the ’80′s and 90′s Pulsar continued to bring to market new products that were born to be different. The Avant-garde collection in 1980′s set a new style in women’s watches and Spoon in 1990′s were unique designs which further cemented Pulsar’s image as an ingenious and surprising watchmaker.

    Towards a modernist future

    Today, Pulsar remains loyal to its heritage. It was born to be different and it will remain so. Each Pulsar watch has the hint of the futurism and modernity that have always been its hallmark. Pulsar is a brand for the individual who appreciates real value and seeks quality with individuality and flair.
